Pontiac: '92 Grand Prix Stalling

If possible, you can unbolt your converter from the exhaust and try to swing
the exhaust out of the way enough to let the converter flow, and see what
happens. Be sure to grab some ear plugs :O)

Do you mean to disconnect the converter from the exhaust pipe as to
bypass it?

The car looses the information that it needs to idle correctly when the
battery is disconnected. The factory manual for it says that a scan tool
needs to be used to set the idle. They call it an "Idle learn procedure".

It has been my experience that the car will idle poorly for the first few
times the car is driven after the battery has been disconnected.
The car should learn the idle information on its own.

Try this: When the engine is cold, disconnect the battery for a few minutes.
Drive the car until it gets fully warmed up. Do some stop and go driving so
it can idle. It may take a few cold hot cycles to learn to idle properly.

Let me know how it works.

I just saw your reply today, but since my posting, I replaced the fuel
filter. It stalled once or twice on me right after and hasn't since.
However, it still hesitates on some stop and go. I also find the
acceleration isn't what just a couple of weeks ago. So the fuel
filter might have been one problem but I feel there's still something
wrong. I couldn't find a disconnect air line anywhere.
