Answer 1

Hi there,

I would start by checking the signal from the cam sensor, also check the timing with a scan tool so you can see if you are losing signal and if the computer is seeing the timing as off. I would replace the sensor as well. It's probably geting hot and then stops sending the signal. A test on the sensor when it's working fine would show it to be good, but when the conditions are right it's failing. If you are 100% sure the timing is on, put a new cam sensor on the car.
