Well, I thought it was the fuel filter but problem persisted. It stalls when I let off the gas pedal, to cost or stop etc. The service soon light pops on for a split second then it'll stall. Takes several attempts to start the car back up.
I found I can keep it from stalling if I keep the accelerator pressed down with out ever letting completely off of it. Even at stop lights (with brake applied of course.)
I'm thanking of changing the EGR valve. If someone could please let me know if maybe the problem could be else it could be. I've seen other suggestion like the crankshaft position sensor. Any and all help is very much appreciated.
Thank you.

Make sure your throttle isn't getting stuck. Usually wouldn't hurt to clean it real well anyways.

Crankshaft position sensor(s). My '98 deville had the same exact problem you're describing.
I was worried about that because is sounds difficult to replace. Am I better off buying a new one or will one from a auto salvage yard work?

I've cleaned the throttle body.

Your car doesn't have CKPs.

First step is pulling codes. Read the "sticky" thread on how to pull codes at the top of the FWD Deville/Fleetwood page. List any codes you may find, AND THEIR DEFINITIONS, here.

Most likely an ISC motor issue.

Well, I pulled the codes this morning and here's what it said:

E52-PCM memory reset
E52-Pass- key control problem
E60- cruise- transaxle not in drive
E63- cruise vehicle speed too high
F32-BCM- ECM data problem

So I'm thinking the big problem is probably the F32 code?

Thanks for your help.
