Smokey Exhaust

[53BigDog]

Ok the other day I notice that I had some carbon residue around my driversides exhaust on the rear bumper. Tonight while sitting at a light I noticed that side's exhaust was "very very smokey" compared to the passanger side, it would cease a second and then puff again....all this while at idle. How do I trouble shoot this problem.

Are you running an O/R midpipe? Because when i had mine, it puffed for abit and smoked but then the computer adjusted and it was fine. Maybe an o2 sensor gone bad

what kind of mods do you have? need some info. and is the smoke white or blue?

Compression test!

Is the smoke blue, white, or grey? Blue = burning oil, White = burning antifreeze/water, Grey = car running rich and dumping unused fuel out pipes (Grey will happen mostly when you are at high RPM and shifting.)

Its Gray and White. Mods include U/D T/A Mac ProChamber, CAI, and Flowmasters

Sounds like you are running rich, but i would say you need to run a compression test.

How old is the exhaust? I know mine burnt all the grease off, so it smoked for a little while.

i have an off-road prochamber too, and mine is smoking too probably becasue i am running rich

Ok Running rich it is, how can you tweak it back?

 

[GreekStang85]

some people say to disconnect the battery for like 5 minutes and the computer will adjust to it or something like that once you connect it back........ just what i heard but i havent tried it.

Yes that will reset the computer, I have done that many many times, however if the error is still there, then after about 10 -15 of driving after the reset, blink, back comes the check engine light.
