Random Stalling
Hello all...I have a 98C5 that has stalled twice. Once it stalled pulling up to a red light and the other was a rolling and go after the light turned green. I am receiving no indicator lights or warnings...the car just shuts off. It fires up on first crank and resume normal operation. Confused on what could be causing this...any suggestions would be appreciated. Thanks!

I guess the first thing to ask, have you checked for DIC codes?

May or may not help - My lady friend’s 98 Grand Prix was doing the exact same thing as you describe – (I mean exactly as you described). Had to replace the MAF. Cleaning it did no good.

Check Batt
I had the same problem with stalling out just momentarily and found the terminal on the battery to be SLIGHTLY loose. Could be your problem, and its a cheap check/fix.

Man,,,thats a tough one. Could be one of 20 things causing it.
Here are some things that I recommend:
Check the wiring harness on top of the engine. The place at the back of the engine where it bends around a black metal bracket can chafe the wires and short out.
Check the door wiring harnesses on BOTH doors. There is a connector that will have a bare wire. The wire is the serial data wire for the doors. If it shorts, some strange things like that will happen.
Just pop out the rubber accordion tube from the door and door frame fish out the connectors from the cavity in the door frame and examine the connectors:
I use liquid electrical tape to cover the wire!
Clean all the grounds.

Clean and tighten your battery terminals, They need to be tightened to 11 ft/lbs.
Hope this helps.
