white white smoke, and car starts misfiring out of control and my car won't idle, it ran fine last night. and i just unplugged the trailing coil and it starts to clear up but it wont idle unless i hold my foot on the gas?

 

just replaced the trailing coil car ran fine untile i reved the car to the redline and it will sputter and more white smoke i doesn't smell like oil my car is a s5 auto

 

i'm have the similar problem mainly in the rear rotor. i can start the engine and it shutters out of control then i can take the leading or trailing coil wire off of the coil and hold the wire close enough to the coil so that the spark will jump to the wire steady and the engines starts to clear up right away . but if i plug the wire back into the ciol it will start misfiring again.

 

Think of bad plug wires????

 

White smoke? Rough idle? Dude, that could be a blown water seal. Coolant in the combustion chamber. If so, it's rebuild time.

 

i just put new ones on

 

i'm no loosing any coolant

 

Dude..... you don't have to loose very much coolant at all for it to smoke like that...., you'd better at least check for bubbles in the radiator.....

BUT.. ATF makes some nice white smoke when you put it in the motor.... don't know how it would be getting in there though..


However... what did you do right before it started doing that?

Check/change your plugs......... and make sure you don't have the coils reversed... trailing = top..
