Ok This is what it does: At idle if you bring it up just a little above idle say around 800-950 rpm's it will flucuate up and down almost like its missing. Thats where its most noticeable. You can also notice it around 1800 rpm.
I've got good fuel pressure, I've pulled injectors and had tested, New Vp twice just to rule it out, cleaned MAP sensor and IAT sensor, replaced the APPS with a williams from timbo, cleaned all my grounds just now. I am running a SMarty on level 3. I have no codes except the 1693 and the other one is a fuel calibration error code and when the rpm's at idle do this weird idle like it misses, every once and a great while it will throw the P0500 speed sensor code and the ABS light will flash once or twice.
The Truck runs great other than that.
Only thing i can think is the APPS might be bad.(I may be having a hard time with the calibration of it and setting the voltage correctly, as when i set it i can't get it to stay at a steady voltage reading.) Or my 2nd thought is the APPS sensor is picking up Voltage output from the alternator from having "leaky rectifiers" in the alternator causing the Apps signal to flucuate up and down.
Just my thought? What you guys think i should try next? Or you think i'm on right track????
