ok
Expert:  Jerry Newton replied 1 year ago.

A common issue on these has been the cam sensor and cam sensor wiring. The wiring itself is susceptible to damage, where it comes down from the intake harness and snakes down to the cam sensor on the front of the engine. Wires break inside the insulation where you can't detect them, things of that nature.

I'd be taking a good hard look at the cam sensor signal on a scan tool, if this were in my shop.
