I have a 91 Pontiac Bonneville. it recently started dying on me while driving I change the alternator and put a new battery in and it still dies my check engine light is on and it reads code 41 I changed the camshaft position sensor and it'* still dies on me. the car will run for about 5 or 10 minutes and then turn off while I'm driving, when I put my lights are air conditioner on or just use any extra battery powered my battery voltage Goes Down. I did the alternator check and my alternator is completely fine. what could it be and what can I do?

Code 41: lost cam magnet in 3800

When you changed the cam position sensor did you rotate the engine to confirm the presence of the interrupter?

Ok so I've replace the camshaft magnet, the check engine light is off now but my car is still dying on me. I can start it, drive for a little while but it dies after like 10minutes of driving. I've put in new alternator, battery, fuel pump, fuel filter, camshaft position senor, cam shaft magnet interpreter, starter. Can't afford to take it to the shop due to the parts that I've already put in.

Just throwing this out there. Unplug the Throttle Position Sensor (TPS) and drive the car (you'll lose overdrive, I believe). See if the car dies as usual or continues to run.

I am not sure if it will run with the TPS unplugged.

It could also be a crankshaft position sensor.

Thank you for your advice haven't tried it yet. But some one also told me it could be my ignition control module but I went and got it tested and its fine although my coil pack is suppose to read 15 and it reads 12.30.. I'm not sure if in my last message it out the check engine light is no longer on after the camshaft magnet was replaced..

the icm and crank sensor both fail warm so the real test would be start the engine and warm the icm with a heat gun carefully and see if it stalls, same with the sensor

My 89 Bonnie was shutting down..I put in a new module and coil.It has`nt shut down anymore .
