2001 Pontiac Grand Am SE1 6 Cyl 3.40L
engine loping,not running hot
I had the typical intake gasket leaking with this engineas u are all familiar with. A month ago I changed the fuel pump then a couple days ago a service engine light came on. code showed vacuum leak on bank 1. engine is flooding and loping with small amount of water coming out of the tail pipe. i noticed 2 cracks in the plenum and replaced it but the same problem is happening. btw i also changed the head gaskets when i changed the intake set. any ideas? I work for an auto parts store and know my way around this car.
