Problem with 1991 Oldsmobile 98

About a month ago the car died on the freeway. It was running on 5 cylinders, so I replaced the Ignition Coil Pack. That worked fine but later that night the car died again and I was told I needed to replace the ignition control module. Done. Since then, the car has lacked power, for example I can only reach 18 miles per hour uphill, and I have a serious loss of flatland acceleration too. I have tried flooring it and once I get to 2100 RPM the car will not accelerate until I release the pedal. At 2100 RPM, the engine makes a steady, loud noise, sounds like a lot of air (just a thought) and after a while there is a faint burning smell. Any suggestions on what it might be?

Sounds like a clogged catylitic convertor. That burning smell is over heating catylitic

    The smell is coming more from the front of the car. I also replaced the catalytic converter about 2 months ago

SOURCE: 2001 focus. Replaced plugs, wires and coil pack.

Have you replaced the timing belt? if not i would highly recommend doing so. these cars need to have the timing belt replaced before it breaks otherwise it can and will cause major engine damage.

My 91 oldsmobile 98 runs rough in idle but when driving run smooth.

Rough idle is a very common problem on 4 cylinders, but I believe the 98 Regency has a 6 cylinder in it, right?

Sometimes the coil packs get iffy, and sometimes the EGR Valve gets a leak in it causing a rough idle.

When the accelerator pedal is depressed, it can change things so that the engine seems to run smoothly.

However, I would look for codes to see if anything intermittent is occurring in the engine that may need attention.

The OBD-I scanner can help to diagnose the problem, if anything is out of specifications on the engine in question.

The owner will have to find a technician that has such a scanner.

Would ignition coil problem cause 2001 Intrigue to misfire?

Not hard at all. Seven bolts and one connector. No computer work. But you need to know if it is the front coil or back coil. Front coil for cylinders 2, 4, 6. Rear for 1, 3, 5.

What is the coil pack for the 88 olds 98

it is part of the ignition system. the ignition system provides spark to ignite the fuel/air mixture at precisely the right time in the correct cylinder. If you have a coil pack you dont have a distributor and the ignition gets its reference from the crank position sensor.

Engine not hitting on two cylinders after replacing cam sensor

If you have a coil pack with 6 cyl. 3 coils in one One coil for 2 cylinders One of the coils in the pack has gone bad. To verify this check which cyliders are missing and see if they match any pair on the coil pack. If so the coil should be replaced. Hope this helped. Moe

While driving, the engine dies.

I had the same thing happen on a 91 Olds 88. Replaced crank shaft position sensor, coil, and ignition module. That solved the problem. I think the culprit was the CSP Sensor, but changed all three so can't say for sure.

Ignition Coil

I own the same car. I would need more info on what happened to be begin with why you think it is the ignition coil.
Your car has an "ignition" ecm (engine control module), on top of that sits your "coil pack" which holds your spark plug wires. If you changed them and crossed your wiring that could be your problem. Let me know I may be able to help you. I just changed both parts on my car a month ago.
