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.
