Thanks for the reply, but I'm still kinda confused.... What does "adjust the base air flow" mean? What wires (color) to check the voltage at? Thanks, Matt.

Replaced: crankshaft w/ DMD, EGR valve (clogged), EVR, DPFE, PCV valve, evap emissions hose & tube (cracked), window regulator (broken), LH & RH PCV tubes, UIM gasket (leak), ignition coil

Not only that but it will throw also throw a CEL if the voltage is over 1.0v at closed throttle. This trick is "suppose" to give you better throttle response as the TPS reaches WOT sooner. What a crock of crap in the first place! You are talking about a change of maybe 1 tenth of a volt (TPS reads around .9v at closed throttle) The TPS reacts much quicker then pushing your foot to the floor anyway. Originally posted by GregH: the only way to adjust the stock tp is to adjust the base air flow... shoot for between .91 and 1.03 volts... The TPS ONLY is an indication to the PCM of the position of the throttle plate. It has nothing to do with nor is changed by incoming airflow! Base TPS voltage is just used by the PCM to indicated closed throttle. It's learned at startup. 2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
