help.....

[kelti819]

so i started the truck this am and service engine light came on, idles rough slow to no acceleration, 2200 rpm at 55mph, checked the codes with my hypertech programmer no codes thrown, checked the fuel filter looks good damn near new, oil and trans fluid right where they need to be. can anyone help please

If the SES light came on, there are codes. The PSD can only be read by high end scanners like SnapOn or AutoEnginuity.

The first thing I would try would be unplugging the ICP and see if that makes a difference. Since it came on so fast, it almost has to be a failed sensor as you would have expected most mechanical problems to come on gradually.

Those dont seem like manufacturer codes. DTCs shouldnt have letters in the middle of them.
