Rough idle and no accelerator above idle
P1120
P1125
P1220
P1281
P1516
Since P1120 indicates that the TPS is out of range, I replaced it. This made no difference.
I thought about replacing the APP sensor in the accelerator pedal assembly but instead of replacing parts that may or may not make a difference I want to diagnose the problem to find the cause.
Any suggestions?
Thanks
