If anyone can help me with my problem I would sooo greatly appreciate it. I have n 03 max that has started randomly started to advance the timing up to 63 degrees from where it should be at 15 degrees. It did this once and then went away now its back again an bad. I had replaced both cam sensors and the intake valve timing solenoid about 5 months ago. At that time I had a code p1120 or something like that. It was one of the advance timing codes. Now I have this killer problem of the motor severely advanced valves tapping and all. PLEASE HELP!!!!

 

So, what's 63º? Ignition or cam timing?
