2000 4.0 Cam Syncro Issues
I'm not much of a poster around here but I do have an issue I'd like some input on. Recently my cam syncro was replaced because of the dreaded sqeaking. No problem there, although the day after it was replaced the Check Engine light came on and gave a cam sensor error. The timing was off a little too, so my mechanic fixed the timing (it was off by a tooth) and cleared the error. The timing seems to be fixed, no backfiring or misfiring anymore and it seems to run fine, however the Check Engine light came back on the next day again. We used a Doorman syncro and sensor, so we though the sensor was bad. We replaced the sensor with a Motorcraft yesterday and the Check Engine light is still coming on with the same cam sensor error.
Not sure how to proceed or what any of your thoughts are. I would hate to dump $400 in a Motorcraft syncro just for the light to come back on again especially since the intake has to come off.
Can anybody shed some light on what the possible problem is?? Could the timing still be an issue even though its running fine? I would hate to have a major mechanical failure driving down the road with no warning. I also can't imagine the syncro is the cause of the problem unless Ford is just nuts about tolerances and the Doorman isn't cutting it.
EDIT: I've had the truck almost 6 years and put 70k miles on it in that time (it has 113k now). Never has the Check Engine like been on until now and the only prior issue was the squeaking. I normally do my own work on it but I didn't want to dive into removing the whole upper intake. I am very familiar with how my truck feels and runs/should run.
Any input is GREATLY appreciated!!!
