I'm experiencing intermittent starting issues with my 1996 GMC Sierra—sometimes it hesitates to start, but runs smoothly once it's running. I'm not sure what the P1345 diagnostic code means or how it relates to this behavior.
No, I'm not sure what it means—can someone explain the significance of the P1345 code in a 1996 GMC Sierra?
P1345 indicates a camshaft-to-crankshaft position correlation error. Common causes include a misaligned distributor, worn distributor gears, incorrect distributor installation, a damaged rotor, or missing hold-down clamp. Excessive play in the timing chain could also be responsible.
