thanks for the response. i used new automotive grade 16 gauge napa wire. and i have tested the tps wires at the ecu on ohms and volts.
i had a 52 code when i first got it running, i rewired the knock sensors with some shielded coax like the write up online.
yea i get the code 51 with the jumper in and opening the throttle at the beginning and the idl opens when testing the tps wires.
the factory tps wires do not have shielding on them. only the cps, o2, knock have a shielded ground around them.
i have preformed the fuel cut test like in the tsrm and the problem i have acts different in person than the test acts.
but i have never heard fuel cut in person so it is hard to compare it to it.
i am going to have a friend come over and help me in the next few weeks. he has a snap on super computer diagnosis tool, hopefully it can read frequency and maybe even o2 like a wideband?

it is getting hard to remember all of the stuff i have tried. between the wiring checks, sensor/parts checks, and troubleshooting.
i will look into the tps and the wiring again.
i hope i can check and see what the afm reads with the hac hooked up and with it unhooked and see what changes.
i originally thought it was the tps but have not been able to prove it was the tps so far.

i enjoy wiring motor swaps as well and diagnosis. but this one is killing me. it has been over a year.
i tried checking the vf signal at the diag port but i dont fully understand where to go with the results i get.
i have wired multiple motor swaps from tacoma 3.4s to chevy 4.3s to lexus v8 to ford i6s. so i am the guy people go to for wiring problems but i have not been able to figure this one out yet.......
