    More Logs

    truck5.xdltruck6.xdlLog- truck5 Is running at 14v with all the adjustment I could get on the TPS. About halfway I went to 12v. Log- truck6 is with the old TPS. I could not tell that the TPS had any effect on the problem other than high RPMs on idle.

    I notice on Truck logs that this is not constant. It is on and off, is this normal? Would anyone have the numbers I should be seeing in these logs. I am thinking about going back to the original ESControl! The NAPA TPS was off out of the box I may just start putting all the OK used parts back on the motor? Suggestions? GS.

    Well here I am July 2018. Some may be wondering what happened with this truck. I put a toggle switch to drop out the alternator so I could get the engine to pull when I needed it. Then in Dec 2017 the engine started to knock so I had a crate motor installed. I told the shop how it won't run right charging and the new motor ran the same as the old one. So as a last resort I swap in the old original TBI injectors that I had changed out in 2013 to NAPA MPF 3-18202. The truck is now running as it did when I bought it in 1993. Can someone tell what is going on with these NAPA injectors? I fought this problem for 5yrs and 2000 miles.
