I recently replaced the fuel pump and that pretty much fixed my cars starting problem. The service engine is still on. Sometimes when I drive the car for a while and park it and then come a few minutes later it doesnt wan't to stay idle it just dies all of a sudden I have to let it sit there for a few seconds and maybe a few attempts. Also when I turn off the car it sometimes chuckles and revs up a little moments after the key is removed from the ignition. What can cause this?

 

What code(s) is being set when the SES light comes on?
