1991 Lumina 3.1L cutting out

Mileage on this engine? One or more fuel injectors beginning to go bad? So far at least 6 have been replaced on our 1990 Lumina 3.1, still running (barely) at

Hi I had the same problem with my 86 Riviera. It sounds like your ignition module is going bad. When youre engine heats up you are loosing spark. I hope this helps Tom

It could be one of many things. However check the simple common things first. Like the condition of your spark plug wires and the spark plugs themselves. A bad wire or plug can cause it to cut out or miss while accelerating.

Once your positve your ignition is functioning up to par you move on to the next step of checks.

Do you have any trouble codes?

Thanks for all the ideas.

The car has 174000 on it, 3 injectors were replaced at

The check engine light has not been on, so I assumed there would be no codes, but I should check.

Seems like people are thinking electrical problem, so I'm going to replace plugs and wires and see if that helps. Otherwise I will likely check into the coils.

Thanks for the ideas.

Good morning, I had the same issue with my 93 Lumina. After replacing the ignition module the problem seemed to go away for a while. It came back and after eliminating a few things we finally nailed what was wrong. It turned out to be the crank sensor. Once we replaced that, the car has been running well. I hope this helps.

Chris; I had the same issue with my 93 Lumina. It turned out to be the crank sensor.

Thanks. I was wondering about that. I haven't identified the problem yet, so maybe that is the problem.
