I have a 04 Sebring. I stepped on the gas to finish out a corner and the enegin wouldn't go. The enegin light came on and when i had the code checked it was a P0300. I have checked to make sure the coils were getting a spark witch they were. I changed the spark plugs. Not sure where to go from here.

 

Did the new plugs cure the problem?

 

no but i found oil on top of the engine. changin valve cover gaskets and intake gaskets now.

 

now it will not stay started. i can get it to turn over but not run.

 

What codes does it show now?
