Question about 2002 Pontiac Grand Am
Cleared codes with obd2 reader. Starts fine, but immediately starts to idle rough. Have changed plugs and coil pack. Car has 96000 miles. Well serviced and has never missed a lick. Drove it home from work one evening, ran fine. Started up the next morning, trac off light and check engine light came on. Have checked wiring, fuses, relays, etc. Ran around the block and warmed up engine to no avail.

The only thing left is the injector or a vacuum leak on the manifold gasket sucking air in and causing a lean condition. Thats is its the only common issue providing you dont have a head gasket issue leaking coolant on that cylinder and the compression and valves are not leaking. The old spark plug should show a coolant issue if present. The white part will be shiney if you have a coolant loss. If the coolant is looking real dark you should have the cooling system checked for gas being pushed into the cooling system on compression stroke thru the head gasket.
