puffs of black smoke??

[Shimy87]

Was following the buick to a car show this weekend, noticed something and have a stupid question. When she would accelerate from a stop using maybe 10 lbs. of boost the car would puff a small amount of black smoke at each shift. Bad thing or normal?? Also when she lifts on the gas it puffs a bit of blue smoke, I knew it was burning a small amount of oil, maybe 3/4 quart in 3000 miles, so I figure that was that issue.

Two different issues. Black usually indicates a rich condition, blue is oil.

You have one of Erics chips in your car...and he errs on the rich side on his default settings...so it may be normal.

watch the 02s when you lift off the gas and then see what happens after the initial lift

[Shimy87]

on a WOT run its between 800 and 810 (lowest recorded reading). I'll  watch see what it reads just after I lift.

running pretty rich to begin with

[Shimy87]

I am still on the default settings, I'll take some fuel out and see what happens. I had so much knock trouble before that I'm probably overcautious.
 
Thanks!
