Truck used to idle, slow down, cough and surge. It would do the surge on idle or driving. I've thrown a lot of new parts at it and have resolved much. But, it still throws the 124 TPS high code (no other codes) and sometimes surges while driving. Lately, it doesn't do it idling. Could this be some kind of grounding issue maybe with the fuel pump? Or would that throw another code?
New parts
plugs (needed anyway)
wires (needed anyway)
TPS
MAF
IAC
DPFE
EGR
EGR tube (needed , broke when I moved it a little)
EGR switch
O2 sensors (both)
Air Charge Temp sensor
Fuel filter
Several vacuum lines (hard ones broke when moving them around)
Vacuum seems good all over now.
Have not replaced fuel pressure regulator.
Not much else to replace or test that I know of.
Any ideas what would still be causing the surging? My wife says it does it when I'm not driving. Guess it likes my driving better
Thanks,
Randall
