So i got an 05 tc with a netics kit with tune.... a little while ago i started to get some random cylinder misfires i would just reset them and move on thinking it was my plugs so about a week later i ordered ngk iriduim 2 steps colder.... installed them same damn problem....so its been about 3 weeks mabye for now and i keep getting this damn code and i haven't been able to figure it out and ive been insanly busy with no real time to investigate it.....well today on my way home i start blowing white smoke out the exhaust whenever i down shift of if i rev it up a bit ill c it.....im gonna start with the gap on the plugs because i don't know what they are set at right now but anyone got any ideas????? thanks in advance

 

What are your AFR's when you see the white smoke?

 

White smoke is coolant.

Are you sure the smoke is white and not white/bluish?

Check your turbo seals.. pull off the intake to the turbo and look for oil. If you can, unbolt the DP from the hotside of the turbo and see if you find oil.

 

ive already blown out the turbo seals once and then netics sent me a new turbo so that may be the reason for the smoke but i don't think that would explain the random cyliner misfires....i could be wrong though.

I know its radiculas but i don't have an afr guage.....so idk what they are when it smokes

 

Hey man check your plugs and wires. Then if you can do a compression test to make sure your cylinders are ok. Its most likely your spark plugs or you have leak in the system if your seeing white smoke. Also get your gauges man their your best bet to make sure your system is functioning correctly.

 

can you read the codes? do you have a scan tool? if you do and the misfire is on one of the cylinders, swap coils and see if the code comes back for the coil you swapped, if the code switches to the other cylinder it's a possible coil

 

ya i have an obd2 reader and its random cylinders its all of them at different times. already did a compression test and all the cylinders are fine....still have to check the gap though.... but would the gap being wrong cause any smoke???

 

I'd check the gap, the gap shouldn't be causing the smoke though
