Sorry, for the delays.
Do you mean off WOT to P/T? There are a few areas and depending on how you are coming off, it could be at said RPM in the very low load part throttle fuel. You could even adjust the fuel in the extreme high load areas of P/T.
Your TPS code. Is there anything happening driveability wise when the code is present? Does having the ICV unplugged prevent the code from appearing?
The 2nd issue you have is strange. I will have to ask Dan what that could be caused by.
right now its when I come off wot but once I am done with that I will tune p/t so both would be good answers.
I get the 1216 randomly but i get it for sure when I go into cruise on the highway everytime. I notice nothing wh cruising. I will unplug the icv and see if it persists. I set all idle speeds at 750 and after the car warms up it goes to 1100 or so but will randomly settle down. I did a smoke test and have no leaks. I replaced the tps.
Im considering data collecting the MAF so I can get some idea of where I am at as far as load when coming of p/t or wot.
also, I triggered the icv in dis and thought I was supposed to hear it. I didnt. I have cleaned it though and it does rotate freely by hand. I could send you a data log of the afr but its too big for the forum (pic).
