Hey everyone. I took my 01 Xtreme to Autozone today and these are the codes that came up. I imagine P1345 is my main problem since my truck is running poorly and the rpms will jump around. So the thing I got says its either: 1. Engine mechanical condition-valve timing off. or 2. Cam sensor or crank sensor are loose on their mounting. As someone with little or no mechanical experience, I say, "HUH?" As someone out of work due to the economy, I seek the most cost efficient fix to my vehicle. Thank you for your time.

 

This should get you on the right path for your codes.

those should get you on the right track. Hell, if nothing else you will have just enough understanding to nod with more than just a blank stare as your mechanic bends you over

good luck, hope one of those helps.
