SOURCE: 2003 MR2 will not idle

I had the same problem. My check engine light was on. Took it to the dealer and they checked the code. It was the throttle control motor failure. The good news is I got the wiring wet and that seem to be the problem. They reset the check engine light and it runs fine now. Bad news is if I had to get the motor replaced they said it would be about $1300.00 I hope things work out for you.

SOURCE: White smoke exhaust

White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event. If its less then there leak coolant leak in the car engine which is causing this problem....

SOURCE: my rx7 blows bule whight smoke when i let off

Hi Ross,

As a rule:

  • Black Smoke = Unburnt Fuel, incomplete combustion, bad mix
  • Blue Smoke = Burning Oil
  • White Smoke = Water Vapor, Water getting where it shouldn't be.
White smoke is common in cold weather when you first start your vehicle. It's from condensation. But it should stop as the engine warms up. If it doesn't, the moisture is from another source.


  1. Are the smoke episodes accompanied by a loss of power?
  2. Was your coolant level low before you changed the coolant?
  3. Did it overheat? Badly?
I'm leaning toward a partial failure of the head gasket. Here is some info, things to look for and tests to confirm.

  • Uncontained compression in one or more cylinders = lack of power
  • Coolant seeping into cylinders through the gasket breach creates white smoke
  • Oil seeping into cylinders creates blue smoke
Things to look for:
  • Coolant levels low. As the coolant is burned off, you'll notice the levels are lower
  • Oil in the coolant. If oil is present in the radiator, it's coming from the engine. Another indicator of a failed head gasket. Only a confirmation though, lack of oil does not rule out the possibility.
  • Water in the oil. Pull the oil dipstick. Is it milky and frothy, like it's been whipped? If so coolant is getting into the oil. Again, an indicator, not a confirmation of a blown head gasket.
  • Is the oil level dropping?
The quickest, easiest and (most importantly) cheapest confirmation of this is to run a compression test on each cylinder. I'm surprised your mechanic didn't suggest it.

The test should show high and fairly close compression (100psi or more) on all cylinders. If any of them are significantly lower, something is allowing the gasses to escape. Since piston ring failures would produce blue smoke, not white, that leaves the head gasket.

If you feel comfortable doing it yourself, testers are available at any auto parts store for under $30.00. If you don't, any shop can do it in under half an hour.

All this is to pin point the problem. Then you know what you are dealing with.

Comment me back with your findings.

SOURCE: 4-3 vortec gas in my oil 1994 s10 blazer . vehicle was running

it doesnt take long to ruin the engine diluting the oil with gas - i dont know how i dodged that bullet, mine was leaking -gas into the oil- new spider is only the beginning of the care and feeding of the unpowered poppit spider motor- regular bottles of injector cleaner will keep them poppits clean, otherwise fuel deposits mess up the quantity and pattern of the fuel spray quickly from new- i had long suspected the new spider i installed was faulty, (Sorensen), but it was just quickly plugged by fuel deposits-as i understand it, the additives often in gas like to hook up in the poppits- my 1994 4.3 S10 kicks **** now, runs like it did when i bought it 5 yrs. ago, smooth like its supposed to, i was chasing the piggy/miss for two yrs, bottles of injector cleaner didnt help, it needed a heavier mix of cleaner
- it couldnt hardly get itself and a little aluminum boat out of a easy boat ramp, what broke free the deposits was doubling up on the amount of injector cleaner i dumped in the tank, when a person takes a clogged injected vehicle to a shop they hook up a pressurized system to it ,and disable the fuel pump -shop air system is better than aerosol can system, force the engine to run on a <10%> cleaner/gas mix for 20 minutes, guess i did get lucky with results from the cleaner addtive, cuz the real fix is find a shop that does the 10% cleaner 15-20 minute pressure wash of the injectors, and it should be done at least every year- mines running so good now, ill not see a lot of results from the pro cleaning i'm scheduled for tomorrow morning - hate to cancel tho- these unpowered poppits are very finicky - i did reuse my plemun half shell gasket, it has the red rubber line on it and it was still live so i reused it

I have Ecort 1.8 td from 2000 Y of production, and have white smoke on pipetail and idles very roughly, engine coolent is OK, oil level is OK, what can it be the problem?.

White smoke and running roughly would normally point to a head gasket problem.

Keep an eye on your engine coolant I'd imagine it will start to disappear.

White smoke cuming out tailpipe 3400 v6

I would almost bet you have a blown head gasket or a cracked head. White smoke at the exhaust, loosing coolant, moisture on the underside of the oil fill cap, and on the dip stick are all signs of a blown gasket. The fact that there is no coolant in the oil does not mean it does not have a blown gasket. To find out for sure remove all spark plugs, disconnect the coil wire, and then run a compression test on all cylinders. If you find one or more with low compression you have a blown gasket. Do not drive this car any longer until you get this repaired. Serious engine damage will occur if you continue to drive it.

Changed spark plugs in 97 buick lasabre and now it cranks and runs, but white smoke coming out. Is that blown head gaskets? Does it have anything to do with the fuel pump my mechanic put on 3 weeks ago???

You need to check the oil with the dipstick (wipe in down a few times) to see if it looks like a chockalate milk shake. If coolent has made its way into the oil you have blown head gasket. The fuel pump which is usually in the gas tank in most gm vehicles would not cause white smoke, if it failed you car would not start because your engine would not get any gas to the injectors
