Just got my GP back from the dealer yesterday because of a CEL. It was a sensor that went bad. Car was running great. Ran the car that day and filled up late at night at a Shell and went home. Woke up for work and car did not want to idle. It goes crazy as in the motor jumps and wants to die. and puffs smoke.

any ideas? going to take it to the dealer monday.

 

black smoke?
= gas
white?
could be normal cold weather cold motor morning start up . if it's a vacuum leak maybe the ecu's dumping fuel to compensate .

 

its blackish..
I think it was a very bad tank of gas.
Dose anyone know a way to siphon gas out?

 

bump

 

Not a bad tank of gas just drained the whole thing and filled up with some new and put some cleaner in.
Sent to mini today hope the find out whats rong.

 

Um, yea. Puffs of smoke are never good, and NEVER gas . Sounds like a sensor took a crap, or you have some type of issue with engine compression. Is your CEL Flashing?

 

The smoke is black? Likely means you're burning oil. Bent Valve? Blown piston?

 

no CEL
I checked the compression on piston 1 it was good but then i had to go. So i dont know about the other ones.

 

sounds like a bad O2 sensor to me...

 

blue is oil black is gas . his ecu is dumping fuel .

 

scan time yeah? maybe the coil is connected badly?
