Any mechanics have the great luck of coming across this issue from one of the 6.0 GM Gasoline Work Horses in your fleet? Accompanying this code is an intermittent loss of power under acceleration which I was never able to replicate no matter how many times I drove this vehicle yet the driver constantly would write it up then we'd red tag it and try to diagnose/repair it. It seems we finally found the problem and its been running its route for the last few weeks without issue. Apparently the wiring under the dash was being affected by radio interference and all the wiring harnesses had to be wrapped in EMI tape and that solved the issue. I know there's more of these vehicles out there and was just wondering if anyone came across this issue also?
