My cobalt ss s/c smokes between shifts. I have been told it's no problem but I'm not sure.Anyone got an answer for me?

 

thats not good go to your dealer ASAP, sounds like the clutch or tranny,but do not quote me

 

probably running rich like most of the ss/sc's out there...

 

is it smoking from the engine, or from the exhaust??? cause from under the hood is a bad thing, from the exhaust would be running rich, but i dont know why you would see smoke in between shifts from the exhaust.

 

If its from the exhaust, thats normal. Slighty rich.. hopefully.

 

yeah mine smokes everytime i shift. it happens with all rich burning cars. its alot of built up going throw the headers, so its forced out all at once...
if you pay attention to older turbo cars with high PSI they spot alot of sult out
its normal... now of u smell somthing cooking, then yeah you should b worried

 

I went to the dealer this week and they said it was burning rich and not to worry about it.The car has only 4210 miles on it.Does anyone else have the same thing going on?

 

yeahhh

 

yea mine does it to but it is white fuel smoke at full throttle speed shifts, all it is is richness

 

Mine smokes a bit too.

I am running rich - av 11.86

I plan to ask about it when I take the car in for this headliner recall.

Maybe an ecm update will help a bit.

 

what headliner recall? the 4door cobalts? what

 

how the hell you know it spits smoke out the exhaust...anyways, mind pops and gurgles so nicely...inbetween shifts...i love it so much...sometimes itll be one loud pop.

 

u spit smoke out when u WOT. all force induction cars do this... its pretty neat accually.

 

Mine used to do that, now it pops flames out the exhaust.

 

Someone runnin a lil too rich..lol...Flames huh?? Damn, remind me not to drive behind you.

Black smoke is the car running rich and bootin out built up carbon. White smoke is burning oil, not good.I believe white is burning oil, either oil or anti-freeze, but pretty sure it's your car burning oil.

 

Nah, its not that bad. Usually only happens when I hit limiter in second or third. Kinda have to do that on purpose. It does smoke pretty good though. You should have black smoke, thats fuel. White is oil like ^^ he said. Even a stock SS smokes pretty good when at WOT. I do love being able to throw flames out the exhaust though. I keep getting asked if i'm the 'yellow one with nos' when I'm out racing. People for some reason don't believe that i'm not spraying.

 

i always thought if white smoke was coming out of tail pipe (while idealing) its water driping... and black smoke is oil driping?

 

If anyone is running rich, it would be me. I'm commanding about a 10.3 a/f ratio but i'm getting about 10.4-10.8 at redline. I'm riach b*atch

 

haha mine dipped below 10 on my dyno run and that was with a sniffer not a downpipe WB

 

Oil burns white smoke, water will be more like steam, white but it will evaporate soon after coming out the exhaust, it will not linger in the air. Black smoke at idle is a serious problem, like a cylinder not firing. You will see some black smoke under throttle, but not idling.

Oil is usually bluish tinged-white
Coolant is usually whitish
Rich mixture typically black
Lean mixture typically brown

Thats usually what i go by.. -Nathan

 

WTF!?

What size injectors are you running?

You're on the brink of flooding man...
