Olds Regency/98 Stalls
1997 Regency. I parked the vehicle for about 5 weeks. I would go out every 10 days or
so and fire it up and let it run to hot for about 15 minutes and then shut it down, hoping
to keep battery alive amongst other preventative issues.
Finally got around to driving it again a few days back. I am having a hard time isolating
this stalling issue. When I am driving up and down main roads, come to a light...its
fine. If I get stuck in stop and go light throttle traffic or if I am doing parking lot
maneuvering with light throttle, when the idle drops down from releasing the accelerator
pedal, it almost seems like the idle just drops out and stall or if it doesnt stall, it barely
hangs on and the engine sputters. If I do this type of driving and shift into neutral, this
prevents the stalling. When it does stall, it fires back up instantly with a healthy
crank/fire.
I have removed a vacuum line, trying to drive the idle up and drove the vehicle and
experienced the same issue. Checked my intake and filter and found no restrictions.
Added some STP fuel treatment to no avail. I am not sure where I should go next as
there are so many possible reasons why this could be happening. Guess I am looking
for some more diagnostic tips from the community on where they would go next on
something like this.
Thank you.
