01 Cummins, de-fueling problem! HELP PLEASE!
#12
I ordered a new TPS, should be in within a couple days. It feels like something is telling the motor to not go, or that its getting mixed signals on what its supposed to do. When i push down on the throttle, it does absolutely nothing for about a 1/4 of the throttle once i get to the half way point. I really hope this solves the issue.

Same issue...
I have the same issue in my 2000 Excursion with a 2001 24v. Runs great with no defueling if the VSS wire is not connected but hits a rev limiter or de fuel at 1500rpm (like limp mode) Now when the VSS wire is hooked up I can rev past 1500rpms but get an intermitent deadpeda, at different throttle positions. I have monitored fuel pressure when this happens and stays pressurized, so it seams lime the ECU is shutting down the VP44.. any thoughts?? Will a bad ECT or AIT sensor could cause this issue? Any help will he greatly appreciated....
