Question about 1991 Oldsmobile Toronado
Have you checked your motor mounts? Stomping on the gas in gear torques the engine. If the mounts are bad the engine will move (it's not supposed to) and this may strain the wiring harness which can then come into contact with the frame or something that could short a wire to ground. It is very unlikely that the problem is in the ignition module itself or any of the coils, as you probably discovered when you replaced them and the problem didn't go away. Open the hood and have someone rev the engine GENTLY while you watch. The engine shouldn't move very much at all. Check your wiring harness at any possible point of contact if the engine does move and look for cuts, gouges, exposed wiring, etc.

chances are the the solenoid that controls the 4- wheel drive is either faulty and causing a short or the wire harness leading to it has a short. the solenoid is a dealer only itm and should be checked by a certified mechanic.. please rate this

There is a fusible link for the blower motor. Check that. Don't know where it is. Look up the wiring diagram at autozone.com. Also check the fuse in the fuse box. Could just be that.

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Torque converter clutch is stuck on. Need to visit transmission shop unless you are experienced with internal transmission repairs.
