Accufab 4150 4 BBL TPS replacement
Do any of you folks know the part number for the Accufab 4150 TPS? I know it is a GM late model TPS, and I bought one from Advance Auto that looks right and fits right (97 LT1 F-body I think it was), but on HP Tuners it reads 13% when the throttle is closed, and then as I push the accelerator pedal it goes DOWN to 0. Have any of you had problems with the LS1 computer reading the correct throttle position on an Accufab 4 BBL?

I think I found the problem: From pics of the LT1 throttle body the throttle position sensor is on the correct side (passenger side) like the Accufab, but the LT1 opens pulling from the bottom rotating in the oposite direction from the LS1 throttle bodies and the Accufab. So, now I need to find out if anyone knows of the same style throttle position sensor that operates in the oposite direction of the LT1 .

Yeah. the throttle body has no name numbers or markings. I've seen some take a ford late Model and some take a gm.. I've got a tbi one coming. Just gonna have to check the volts and % when it gets here.. bought the car with few mods, gonna have to learn more about it lol
