Rough Idle and Rough Stops

[Trussell]

Hello

I'm having some problems with an 09 Cobalt LT

After the car has been running and is up to temp, when I restart the car it tends to have a rough idle...it seems to have a misfire but the tach isnt jumping....once the car is in gear it seems to smooth out

Also when coming to a stop, it acts like it wants to stall but so far has not

any ideas what could be the cause? I have done the regular maintenance

Car is a 09 Cobalt LT Automatic with 108,000 miles...its daily driven mostly highway miles

Thanks

Clean the throttle body.

Quick question

is the throttle body located off the air filter box or at the front of the motor?

Thanks '

throttle body is sitting on top of the intake manifold and underneath the intake system.
