Dieseling Engine overheating? Engine idling too high? Try a higher octane fuel?
This may not be your problem but I had this problem with an '86 Dodge Colt. Turned out to be the timing belt.
I just fixed mine! Remove the panel over pedals by removing 4 screws with a 10mm socket wrench. Unplug the white plastic plug that has two blue wires that attach to the ignition assembly. This also disables the chime that rings when you have the door open with the key in the ignition. You can test it before you put the panel back. This job took 10 minutes. I had already replaced the entire ignition assembly, which did not fix the problem.
you have an engine/ignition problem. HAve a garage read the codes and diagnose the problem soon.
the ignition switch is bad. you have to replace the ignition switch and you will have to have a new key made with it. i just replaced it in my 1992 seville. that will solve your problem.
Sounds like an ignition problem. Something is heating up and opening electrically. Could be a magneto/ignition coil, capacitor, plug wire. Tom ♥
its either the starter or your ignition
Physically has a turning problem ? Try your spare key and still has the problem? Replace the ignition switch.
ignition problem
it sounds like your ignition switch, i ran into a similar problem, your power goes through your ignition switch for your blower motor.
fuel pump probably, common problem among later model impalas
ignition problem
I have the same problem with my 2004 Sunfire. Leave the ignition on for 10 minutes. Just let it sit for 10 minutes. No shorter than that time. And Should start.
