I hate to post another cam sensor related thread but I wanted to see if anyone had any thoughts on an issue I've been experiencing before I go hanging parts. I pulled my engine out last winter to do some minor clean up work to both the engine and the engine bay. Every since I've got the car running again it appears to be running great for the first 10-15 minutes and then it starts missing, throws a code 41, and then goes into limp mode and won't start again until i reset the computer. I've set the cam sensor twice, the first time with the lining up the dots method, and the second time with a volt meter. It's getting good voltage to the sensor, all the grounds are hooked up tight including the two bolts on the back of the head, the ground on the turbo bracket, and I have a ground strap from the intake to the firewall. There's nothing on the scanmaster that is alarming, crank sensor checks out ok but I haven't taken a close look at it. The car runs better than it ever has before the issue occurs which makes it hard for me to believe the sensor is bad when it ran fine before I took the motor out. If the sensor is bad wouldn't it have the issue all the time and not just in closed loop? However, I don't know what else to check, the no start tree at vortexbuicks points to a faulty cam sensor as well. The last time I had the sensor out the gear did not look worn and it had very little vertical play. The sensor cap has always had a small crack in it but it never caused an issue before. Should I just buy a new sensor or has anyone else had this problem?
Thanks in advance for any input, there's nothing more frustrating than having your car apart all winter and still not being able to enjoy it once you get it back together.
