Hi, I've got a 1994 BUICK PARK AVENUE V6-3800 3.8L, and it's stalling on me pretty frequently. The car seems to idle and accelerate fine. However, if I use the gas pedal, then once I take my foot off the pedal, the engine stalls. If I let it up slowly and carefully, or if I'm just driving slower, sometimes it won't stall, but the rpms will drop low and the lights will dim for a second before they go back up.
I've checked my PCV valve, replaced my spark plugs, and used some wire dryer, fuel line cleaner and gasline antifreeze.
At this point I took it to a mechanic. They cleaned the throttle body and mass air flow sensor. Didn't help, so I brought it back. They replaced the IAC motor. Still didn't do anything.
Any suggestions? Thanks.
