So do i have to do that with every sensor or just one sensor?THANKS

Forgot to put that in there...When i did the VP i also changed out the cam sensor as well since its right there. My truck details should be in my SIG? They not there? Truck Details: 2002 Dodge 2500HD, Di-pricol pyro, boost, Fuel pressure, Mach 1.6, Rip's 4" Exhaust, Raptor Lift Pump, New VP at 83k, Liner Sprayed N-fab Steps and Rockers. mostly stock for now.....94k on the clock as of now. How exactly do i do this step by step.... "Make sure you grounds are good... The master ground for the engine is hidden behind the starter. This has the ECM, and all the sensor tied to it. You should be able to put a POS probe in a ground connector of the sensors and the NEG probe to engine block and show 0.00 Volts if this rises above 0.20 Volts then you got a bad ground." POS means???? Valve Adjustment directions? Thanks.

Nobody????

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????
