-Car will start and sometimes, only has happened twice now, but it will start and die instantly.
-Car idles rough.
-Car gets bad gas mileage. The DIC says otherwise, 32MPG, even after being reset, but it's definitely wrong.

Not sure whats wrong. Plug is fouled? Injector is fucked? Fuel filter is clogged? Butterfly on the TB isn't closing all the way? I have no clue.

The car only has 19,000 miles on it.

The TB is clean. Air filter is clean. MAF is clean.

Maf is clean but might be no good !
How does it run otherwise ?

injector maybe? have scans or anything?

Try replacing your EVAP emissions canister located directly to the right of your valve cover.

I had a very similar issue, cept. my car would only idle rough or shut off right after getting gas.

Runs great other than the shitty idle, and the fast that at WOT it feels like a total turd. I mean I know it's a 2.2L, but it used to have a lot more pep.

What do you mean scans? There is no CEL, if that's what you mean?

How much would that cost?

fwdGTP

i ment like an HPT log file or something so you could see what's going on with the car.

Steven Flit

to be honest I do not know... my friend had a spare one.

Go to your local dealer and ask, or find out the part number and look on gmpartsdirect

I might just bring it in.. I really don't feel like going on a goose hunt, when the car has a warranty.

I'm going to place my money on it having a bad plug or a bad injector.

I would try resetting the computer by unhooking the battery but I was told that doesn't reset it, the Cobalt stores it somewhere in the event the battery is unhooked.

Hey guys I have a 2006 2.2 chevy cobalt and I am trying to change out my spark plugs but when tryig to twist them out the socket wrench won't budge. I am using all the right tools. Does anyone any tips that could help me on this project?

Are you following the Righty tighty lefty loosey Rule ?

If you think they are seized you could spray wd40 on them and let it sit for a while,but from my experience it doesn't really help. Get a bigger Ratchet!!

If they are that tight you might have a issue and they will strip out.

Aluminum likes to stick to steel(The term for it is galling)

RacinJared

Yeah I using the lefty loosie righty tighty rule. I will probably have to buy this product that is like wd40 but its stricktly for bolts and things that are really tight and hard to get off. But thanks for the idea though.

If you can get your hands on an impact wrench you could try turning the torque all the way down and it might break them loose....gotta be careful though

It could be all those...clean ur airfilter and get new plugs. My buddy had a srt that did this.
