Other codes for knock sensor circuit high. I assume due to the engine noise. Just came from the dealer for a drive by wire repair. Looks like they replaced two wires from the throttle body to the pcm.
Sounds like it jumped time or a chain is loose. What next, Tear it open?
I was just going be the info supplied, sounds like a chain issue. These had alot of trouble with the upper chain tensioners and chains stretching. We see chain tensioner issues on alot of different brands and normally upon disassembly, plugged/restricted passages are what we find.
