This is the third timing chain I have replaced on this truck. the first two went flawlessly. Also, replaced CSP sensor, all four oxygen sensors and air idle sensor. Truck ran fine prior to change now runs extremely rough. Suggestions?

Hey Bob,

This sounds like you may have bent a valve, lets do a compression check to see if there are any low cylinders.

Here is a guide to help
