Hey everybody, new member, long time car guy. Grew up with a father who was a Master Technician and Instructor. Rebuilt many an engine and drove many different vehicles in my 54 years.
The Problem: 04' Bravada bought new, 195k miles. Paid independent shop of good rep to replace timing chain. Chatter gone. Deeper problem, searching idle & stalling, shop sent to dealer connection for re-flash for searching. All said & done P0016 code, cam/crank correlation. They throw a cam solenoid at it, no fix. We drive it for a week, runs better, better fuel economy, But, Cruise Control is now intermittent. I verified cam sensor working personally with a scope-meter, if crank sensor was bad it wouldn't run. I also verified continuity from the Cruise switch assy to the ECM. Took it back to the shop this afternoon who sent it back to the dealer for further troubleshooting. Shop gave us one of his trucks as a loaner while it's back in. Shop affirms they used proper cam alignment tools for the chain & replaced the seized cam-adjuster which includes the cam sensor reluctor. Everything I read points to improperly aligned cam.
Thanks for any help.
