I sell them but don't work on them. All vitals, fluids, hoses are fine just no throttle response. My mechanic friend got a scan code
1576 as noted above. Engine idles perfectly but message center onboard started going in and out of "Failsafe" witha "Yellow" guage light adjacent the message center. During the lengthy trip home it continued running alright but throttle response became intermittent and the yellow warning light on the left of the message center now went to a red light to the right of the message center and eventually led to no throttle response. MY QUESTION IS what part/parts should I have him replace and where can I download an instructional diagram for this repair short of buying a whole tech set?? Many thanks!
