1999 Park Ave 3.8L suction sound from intake upon shutdown?
the title pretty much says it all. ive been unplugging sensors and stuff trying to figure out why im getting bad fuel economy but they all look ok and when disconnected the car hesitates. but anyway when i turn off the car there is a release of suction sound from the throttle body. any ideas? it tends to do it more when the engine is warm. thanks alot!
