My car is fine when I'm giving it gas but promptly dies as soon as I am not. Needless to say this is quite a headache when driving in the city since every red light, stop sign or slow down means I have to restart the ignition.
It also shakes like crazy when in neutral (but nmot when in gear) altho that may be an unrelated problem? From my very limited knowledge of cars and past experience I suspect the constant dying is due to the spark plugs, which have not been changed for well over 2 years of heavy inter-provincial driving. Attempts to discuss this with the local "mechanics" result in utterly blank looks. I have tried " sa-PARK" and pictures of same with no luck. Questions: 1) Am I right that this is a likely cause? and 2) How do you say Spark Plug in Thai?? Appreciate advice #2Posted 2008-06-04 14:26:41

Spark plugs along with all the othe High Tension leads coil distributor cap ect useually breakdown under load,
Sounds like it might be the carb tickover [idle speed ] might need a tweak, or the slow running jet is blocked, or the intake manifold is sucking air, I would have these checked first, and after 2 years it woudnt hurt to replace the spark plugs, Cheers, Lickey.. #4Posted 2008-06-04 14:54:44
Memorise all of these, there will be a test next week.

yes "hua tien" aka "head candle" is correct for "spark plug."
As another poster mentioned, Sheryl, I would check the idle speed controller (or whatever derivative of such your car has -- older cars as mentioned above may have to adjust the "carb tickover" but newer cars may just need a shot of Sonax through the idle speed controller. Does your car have a rough idle (do the rpms fluctuate up and down when at idle)? Does it idle roughly and then stall at the low point? If so, I don't think it's a problem with the spark plugs, but rather a form of idle problem or distributor problem (if you have an older car). Maybe we could better help you out if you gave us more info on the car. apetly: there is one part not on your list that I had a hel_l of a time explaining to my mechanic what it was: control arm aka "peek nok." It took some time to get from McPherson strut which he knew to saying "ok, not McPherson" to me drawing a wishbone x 2 , using my fingers on top of one another and moving up and down and saying "race car suspension" and then finally pointing out the part on the lift. "Peek nok" haha... #6Posted 2008-06-04 19:17:39
I had a similar problem on my old mini in Australia. It was to do with the electic fuel pump and poor wiring to the pump. I found this problem on the start to a 300km round trip and had to keep giving in the gas at speeds up to 120 km/h. Everytime I was just cruising it would starve and would have to pump the pedal a bit. A few new wires and it was put right. What car do you have? It's hard to give advice without more information.

It's a Sunny Nissan, manual transmission, very old (late 1980's I think).
And indeed, trouble was not due to the spark plugs as the two magic syllables "hua tien" did indeed achieve their replacement and the problem persists. It makes a huge racket and shudders when in neutral. No problem when in gear. As soon as not getting gas, regardless of whether in gear or in neutral, it dies and I have to turn the key to re-start it. As long as it's getting gas, it's fine. A little slow latley in starting up, too, but it does start. Teej...your terminaology is a bit hard for me to follow but I think the "idle roughly and then stall at the low point" is probably the one. If by RPMs you mean the speedometer, that's at 0 when in neutral (or dropping to zero if I am just slowing down). It will hoever die even short of having come to a stop, for example when I stop giving gas and break to slow down on a sharp curve, it dies on me. Basically as soon as my foot is off the gas pedal for more than a second. Apetley, many thanks for the vocab -- sorely needed -- can you add to it: carb tickover slow running jet intake manifold In case any of those are indeed the cause. I have to admit I am clueless as to what any of those three even are, let alone how to say them in Thai. I live just close enough to Bangkok that every mechanic with half a brain has gone off to work there and just far enough away to have to rely on local repair shops. The quality of which defies description save to say that even I know more than they seem to, and like most women, I know next to nothing about cars. #9Posted 2008-06-04 22:21:14

Sorry Sheryl for not clarifying. By RPMs (revolutions per minute) I meant the other dial on your dashboard right next to the speedometer. It shows how much you are "revving" (as you press harder on the accelerator, this dial will indicate a higher number). So at idle, it should be around 800 (usually the numbers shown are 1 through probably 6 (with writing somewhere that says "x1000").
So at idle, the needle should be below "1" or at least close to it. If this needle is dropping below, say 500, and coming up again, then dropping, this could be considered a "rough idle". I suspect that the huge racket and shuddering while in Neutral is followed by the engine dying? That is because as the car idles too low, it struggles to stay on, but for some reason (the problem we are looking for) it can't and then dies. A dangerous condition especially considering that you mention it dies if you're not giving it gas on a turn -- bad situation. Maybe another member can pinpoint what mechanism controls the idle speed in that particular vehicular make and model. However, I suspect (hope) that it's just an idle problem (which shouldn't be too costly to fix -- unless you have a SAAB Whereabouts do you live? Maybe another member can recommend a garage in your area, as it's a problem you need to get fixed asap. I think any fairly competent mechanic should be able to sort it out for you. Last resort: ask a Taxi driver who drives a similar make and model. I've seen some Nissan Sunny taxis. Maybe they could point you in the right direction. Could be something wrong with sensors like oxygen sensors, etc. but I still think it's an idle control issue. If so, it should not cost you more than a couple of thousand THB to resolve. Maybe another member can offer better advice than I can, as we have some pretty good knowledgeable members on this board and I'm no mechanic. Good Luck #11Posted 2008-06-04 22:48:51
I know it's as easy to say as it's difficult to find, but i think you have to find someone who understands cars to have a look at your car. Otherwise i think you might end up replacing parts more or less forever...
Your problem might actually be corrected very easily and with very few tools and parts provided that you've found the right person. I know a guy like that in Chonburi, but maybe that would be too far? /Hans

Sheryl, are you dipping the clutch and keeping it down allowing the engine to die on sharp curves ect? dip the clutch, change gear if you need and let the clutch up to keep the engine spinning and responsive.also if you know yove got to stop, select neutral, brake with your left foot and feather the throttle gently to keep the engine running,
The latter is a GET YOU HOME GIMMICK till you can get it repaired. Or remove the air filter or pipe whatever is on top of the carburettor, get somebody to operate the acelerator and watch the movments at the carb, you should see a screw with a spring on it moving with the linkage, this is the tickover screw or engine idle speed screw, turn this clockwise half turn then start engine, if its ok, good, but if not turn in a little more, if you have to go over 12/1300 RPM the problem is inside carb. Does your car have a manual choke? [probaly not} but if it does, this has the same action of raising the idle speed, to cope with the extra fuel, try pulling it out a bit then go for a run. If this all a bit beyond you, perhaps print it off and show a falang friend, Good luck, Lickey.. #13Posted 2008-06-05 07:24:42

On a Nissan I owned I had nearly identical problems which turned out to be a loose plug on the side of the carburetor. The plug was part of the heat sensing system for the auto choke.
Take a look on the side of your carburetor and see if there’s an electrical plug and that it’s pushed in firm. I also found the female connectors inside the plug were loose and needed a slight squeeze for them to make contact correctly. If that doesn’t fix the problem I’ve added some information from the Haynes 1980 thru 1991 Nissan Pickups Automotive Repair Manual that may be of help. Troubleshooting Engine stalls 1. Idle speed incorrect 2. Fuel filter clogged and/or water and impurities in the fuel system 3. Choke not operating properly 4. Damaged or wet distributor cap and wires 5. Emissions system components faulty 6. Faulty or incorrectly gapped spark plugs. Also check the spark plug wires 7. Vacuum leak at the carburetor, intake manifold or vacuum hoses 8. Valve clearances incorrect This is a shortened version of the Nissan Service Manual diagnostic procedure for 1990 models. Engine stall after deceleration 1. Check A.A.C. valve 2. Check idle adjusting screw clogging 3. Perform power balance check 4. Check ignition spark 5. Check fuel pressure 6. Check harness connections Hope this helps #15Posted 2008-06-05 09:20:01
this might help with translations of engine parts into thai.

Do all Japanese cars have tachometers that show engine speed? My 1997 Nissan NV does not. And we can assume a late 1980's car has no fuel injection, and not many computerized engine controls.
Ever since they went to electronic ignition in the 1960's and did away with distributors with contact points, spark plugs seem to last far longer. Still, they should be replaced, along with the plug wires, every few years. When we bought the NV used, that was a standard repair to get it running well. Carburetors - I hate them.

The only dials next to my speedometer are the fuel gauage (left) and the temperatire (right), I don't see any dial such as you describe. Yes, the huge racket and shuddering is followed by the engine dying. I live in Prachinburi. I realize I need to find a decent mechanis and if anyone can recommend one in prachinburi I'll be eternally grateful. The thing about travelling far afield, aside from the time and inconvenience is that it is hard then to go back if things go wrong and there is less accountability when they know you live far away. I had my clutch replaced in Nakhon Pathom once only to have them call me when I was 2/3 the way home to say they had "forgotten" something (turned out to be a major costly part for whicvh i had already paid) and would I just "frop by" for them to correct it, which of course I couldn;t so I ended up paying twice for the sasme part and labor. the local folks while (a) a few sanwiches short of a picnic and ( How to say "idle speed" in Thai?

Sheryl, have you tried taking it to the local Nissan dealer? It may end up cheaper than making numerous visits to the local backyard mechanics.

It depends if Thai or English is the reference point, of course, but i think air filter was in the list already, wasn't it?

No! Please do _not_ suggest anyone to drive an automatic car with both two feet! It can easily turn into a disaster!
I don't believe in breaking a manual car with the left foot either, of course... /Hans

Sheryl, please give us an update when you have the vehicle looked at.
I can't speak for anyone else but, I'm on the edge of my seat. Hard to say from the general symptoms, could be anything from a vacuum leak to losing power on a cylinder. Take the beast to the shop. #25Posted 2008-06-08 18:32:32
Will do but alas, very close friend required major surgery and as she speaks neither Thai nor English I have had to be with her 24/7 for all the appointm,ents, work-ups and then the surgery...ther first 2 parts of which involved daily travel of 500 km
Don't worry, I have giotten quite adept at managing the clutch and brake tricks (and it's a manual, not an automatic, Hans!). But I will indeed get ot looked at as soon as I can, Knock on wood my friend will be discharged tomorrow and once we've weathered the drive back to Prachin I'll have time to get the car looked at....... Will let you all know trhe results |
