Recently did a cam swap on car, afterwards it did fine no problems. Then the tach started acting erratically, plug scanner in it reads rpm fine but shows cam position signal dropping intermittently, more so when the motor starts to heat up. Have changed cam phaser, cam sensor, tune, checked grounds, checked wires, and dealer verified cluster was good. Any thoughts or ideas would be greatly appreciated, as car has been sitting in shop for 3 weeks for this problem. Thanks in advance. Oil gauge also fluctuates between 20-40 at idle while this problem is occuring.

Just curious do you have long tube headers? If so did you make sure that the wiring harness on the passenger side has not melted from the heat and has ample clearance.
