06 Cobalt rough idle and smells hot

Asked by Dec 19, 2015 at 10:10 PM about the 2006 Chevrolet Cobalt LS

Question type: Maintenance & Repair

My 06 Cobalt started running rough and also dying at stops. It only seems to
do this after the engine is warmed up and has been driven awhile. I also not a
burning smell after this only outside the car. I cleaned the throttle body and
changed the spark plugs with no change. Does not seem to matter if air or
Heat are on or off. When this occurs I get a engine light that reads as a
general misfire.

Could be lots of things. You need to get the codes read to see what the computer is saying. It's likely an electronic issue of some sort although a plugged catalytic converter springs to mind as well.
