My 09 is an auto and the other day I got in it and when it hit second,it shot out a puff of black smoke. A friend saw it happen. Happen to anyone else?

 

I think it's pretty common. Something to do with the direct injection I think. I know you will see a puff of smoke upon startup if you look closely.

 

it happens when it gets overly rich its "normal" for our cars....dont worry

 

Okay. Thanks guys.

 

Its especially noticeable if its cold on take off, let your car warm up a bit before flogging it.

 

Yes I saw the same thing happen when what looked like a 2LT try to merge on the Merritt Pkwy in CT. The kid gunned it (he must've been a lot jockey swapping cars w/ another dealer, the HHR had dealer plates on it and the OEM sticker in the window still) and you saw a big cloud of black smoke come out of the tailpipie.

 

It happens on my 87 5l occassionally. No big deal

 

I do see a "puff" sometimes when it's cold, but never something that could be characterized as a "cloud".

 

Well, I would have to say it is normal; my exhaust tip is BLACK after just a few hours of drivin' What about you? Turbo has a lot do with that along with direct injectors.

 

yeah, that's pretty normal LNF behavior. run rich on start-up, plus being DI, nothing to be concerned about.
