I have a 1991 pontiac bonneville with a v-6 engine.

It could be the ignition module in the distributor or the pick up coil mounted under the distributor on the shaft. could also be the coil you may need a mechanic

your son's car either needs a tune up or could be a broken,*****, or desconnected vacuum hose or, even the idler control valve,

Have the diagnostic connector read to find out what the problem is.

Sounds like the engine is starving for fuel - plugged fuel filter, failing fuel pump, malfunctioning fuel regulator, etc. Have the fuel pressure checked.

ECM fuse 25 amp, under dash

If your check engine light is on, find out the codes. I would have the fuel pressure checked again, first run the car until it stalls again and check it. I've installed pumps that went bad in as little as a couple days

Check the egr valve by located it and the vacuum hose connected to it. pull of the hose and check it for wear like cracks or hardening of the rubber. If it looks ok, reconnect it to the egr and start the engine while it is cold and with the engine idling, remove the hose from egr valve. If the engine sputters and then dies, pull off the vacuum hose one more time and try to start the car. If it runs fine with the hose disconnected, replace the egr valve.

I have a 2000 Bonneville - I had a problem with the car stalling out - then it did not want to start back up. (When it did it would idle up and down and then die) I changed out the mass air flow sensor - now I have not had a problem. Good luck with it.

check your catalytic convertor for blockage
