Exhaust Smoke

[Matt G]

Is it normal for a firebird to have a little tail smoke at 4000 rpms and up?

[RicE-ter]

if its running properly, burning most or all the gas in the combustion chambers, i see no reason it should have ne smoke after the car has warmed up.

does the "smoke" have a distinct blue (oil) black (unburned fuel) or white (coolant) hue to it? If so it's not normal.

Otherwise, I'd chalk it up to cooler weather.

would a bad cat cause black smoke on hard acceleration?

[Matt G]

it is a grayish white color that only comes out when i am above 4000 rpms. I knowticed it on a cold morning so that may be the reason. I will rev it on a warmer day. What should i do if the gray smoke is not from the colder weather?

97rs... did you paint your own interior or order a kit?

[97rs4life]

painted it myself.

Make sure it's actually smoke and not steam. Steam is normal and will dissapate, smoke will not.

[Matt G]

Okay, then it is steam because it gets up to my spoiler and it disappears.

Steam forms on cold mornings and when your car is cold. a little repspiration happens at the end of your pipe and does it until the inside and the outside temperature evens out, sort of like the windshield
