Trying to figure this one out for a friend, get a cylider 6 misfire and injector circuit open code.
Happens when...
Hot
Under slight load (like uphill on highway)
Never when...
Cold
high RPMs
Switched out injectors, still remains only on 6. Wrapped injector 6 in header wrap to prevent heat from manifold reaching it, no go.
Plugs are fouled with ash/soot.
Doing a compression test tomorrow, hoping it's not valve related.....any other thoughts?
