Adjust screw until the voltage reading indicates 1 volt.

Hey satch... If you got a nickel for every time you posted about proper TPS adjustment, you'd be a very rich man! Heh'

If you can smell fuel then I suggest that you check your fuel lines, rails, and injectors for leakage.

All the ISC does is disable the BAC. Nothing more.

Adjusting the variable resistor will only effect your mixture at IDLE and no where else.

Bumpstart, who seems to very knlowlegeable about these cars, says otherwise. Also, if I were to go way lean on the setting and then take the car for a drive I will find that the car gasps for life at the high end of the rpm range as if it is being starved while when readjusted to a richer setting the car will not act as such at all.

Well, I am telling you thats not true. The only thing that the ecu uses off of idle is the TPS (marginally) and the O2 for cruise. Everything else is in the lookup table not effected by the variable resistor.
