Question about 1991 Oldsmobile Toronado

1 Answer

On My 1991 Olds Trofeo 3.8 If I Drive Realy Easy It Runs Fine But If I Hit The Gas Pedal To Fast Or Hard It Blows A Fuse That Powers The Inighion Moduel Then It Dies.If I Sit Still In Neutral And Gun The Motor All I Want No Problem, But If I Try To Take Off Just A Little Fast Bam Fuse Blows. I Put A New Inighion Moduel In And All 3 Coils But It Did Not Help.Anybody Ever Come Across This Before?

    Thank's for the idea,but I figured it out before this was sent it was the wiring harness grounding out at the back of the motor but not because or motor mounts.It was to tight running down the back side of the motor so I made it longer and now everything is fine.

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.

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.

SOURCE: 1993 olds cutlass supreme 3.1 multi port loading up at idle

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.

(#23fuse)No turn signals/backup lights - keep blowing fuse. hard to get out of park.


You have a short to ground on that circuit , you need to look at a wiring diagram an see what all is on that circuit . It's hard to get out of park because this circuit supply's power to the shift interlock actuator . You don't need to step on the brake pedal for this fuse to blow ? just stick in a new one an it blows ? This fuse also powers the brake switch , which powers your brake lights .

I would make sure the firing order is correct. It is 1-3-4-2. If that's OK I would check for a valve train problem such as a worm camshaft.

1991 Accord, ECU fuse is blowing, checked wire from fuse to main relay, ok, tested with another relay, still blows, any suggestions?


Check the power wire at the computer for a short. The computer itself may be bad, causing the fuse to blow. Unplug the computer and see if fuse blows, if it still does, it would probably be in the wiring from the relay to the computer.

You have a large wire that powers the ECM, it has rubbed through and is grounding out and blowing the fuse, locate the power source for the fuse under the hood, then look for damaged wiring, check places were the wires touches the body, it will not be easy, it takes time and a keen eye.
