2011 GMC Acadia P0008 Code: Rough Idle After Timing Chain Replacement

Model: 2011 GMC Acadia Fault Code: P0008 Posted: 2017-10-29 12:31

My 2011 GMC Acadia recently had the timing chains replaced and reinstalled. Since then, I've been receiving a P0008 diagnostic trouble code for Bank 1, indicating an engine performance issue. The vehicle runs smoothly at higher idle speeds, but exhibits a rough idle when idling at a stop or on a curb. I'm looking for reliable troubleshooting steps to diagnose and resolve this issue after the timing chain work.
