Looking to get a little more detailed information for troubleshooting this issue. Im pretty sure ive narrowed it down to a section of the truck but looking for confirmation.
Recently truck has been shuttering while accelerating or starving for fuel. At 2500 rpms it just stalls but revs a little and won't accelerate. While it "seemed" worse lower the tank but thats not the case. Tank was at half when I started noticing the problem. Noticed really bad when going up a bridge and the truck would not accelerate, but think it was coincidence. If I go full throttle the truck loses power and once even cut off on me. Put in neutral and fired it back up with no issues. No code has ever been thrown or read in the background.
Fast forward today and I started getting voltage readings on the TPS to narrow it down. Put a meter on the grey wire which is my understanding is the power wire and got 5 volts (Good reading). Went and checked the black wire (should be ground) Ohmed it out so that left the other wire that runs to the PCM. Controlled throttle by hand and it was a steady increase to 4.5 volts with no stoppage.
Truck has a new battery, new plugs, rotor, fuel pump and fuel filter in the last couple hundred miles. Spark plugs changed on 9-13. This has been in the last tank or two before that it was running good. Its only my weekend truck.
What should my next step be?
***updated for things checked and changed***
Thanks TJ
