:My drivers side cam (?) crank angle, sensor broke. I have tried two more replacements so far. When I start the car with the transmission in neutral, the rpm goes straight up to redline. When I put it in gear, the rpm goes back down. However while driving the rpm won't climb above 3k. I have checked all the plugs, and they look fine. Thanks for your time everyone. :Not sure if he means the cam sensor on the back of the head or the cas in the front. the one in the back
