1991 Oldsmobile Cutlass Ciera Question: Stalling

looking for advice, my vehicle stalls while driving and at idle on a regular basis, i can't get a diagnostic because the wiring for the cig lighter is ripped out, how can i get a proper diag if i can't get a computer on it -
Answer 1
You should still be able to access the engine computer of your 1991 Oldsmobile Cutlass Ciera with a scan tool or code reader. What you will need to do so would be a cigar lighter adapter which will connect directly to the battery, they should be available at most auto supply retailers. Common problems causing a stalling condition with your Ciera would be an internal distributor fault, faulty engine control module, or a sticking torque converter clutch solenoid. If you can give a little more description of your stalling condition I may be able to offer more help. Questions to answer would be: Does your Ciera stall when exiting the freeway after driving for 20 minutes or more, and what happens when you try and restart the engine? -

definetly stalls when driving for 20 min. or more then coasting off an exit. i also feel it sputter(like a miss)a few minutes befor it does that. the situation is progressing. i didn't even have to drive it very long today before it stalled. that was about a half-hour of driving around the city and would stall at a light while idling. -

Have 91 Olds Ciera 3.3 with exact same symtoms as above. Vehicle does however start back up after engine cools down but will eventually cut off again. Fuel pump & ignition module replaced. Any help or advice? -
Answer 2
Same problem I had. I spent over $2000 on it before finding the cause. It was a bad multipurpose ground on the transaxle housing. Pull the air cleaner assembly off, dismantle the ground, clean it all up, and reattach it all. Be sure to disconnect the battery first. This ground is a pain to get to, and you have to use a backup wrench on the larger post hex in order to unscrew the pressure nut, or you'll rip off the connection eyelets. Ask me how I know... The ground post is located under the air cleaner, and under the crossover exhaust pipe. -
