Just rebuilt the Engine (4.0 l). Cam position sensor position wasn't marked and removed while engine was not at TDC. Looked at every thread I could to reinstall and tried to get it to 0 degrees toward the back. Jeep fired right up but now is missing at idle, and when greater than 2500 rpm. Any ideas on how to get it dialed in or if I'm barking up the wrong sensor tree?!?
