I Just purchased aAcufab Single Blade Throttle Body and I took my TPS of the stock throttlebody and put it on my new one and now my car is Idling high how do you set the TPS so that it will idle right? And one other thing is if anyone that has used a acufab does it shorten the pedal cable to cause it to be shorter?

its not the TPS thats causing u to idle high. screw the adjustment on the bottom of the tb to fix it. because the throttle body blade is letting in too much air at idle
also might want to try resettin ur computer so it can adjust to ur tb... just a thought...
+1 Although when I pulled my TPS sensor off my stock t/b and put it right back on my idle went high too. No codes or anything and had to actually buy an aftermarket one so I could oval out the holes to be able to turn it enough for the idle to drop. That was a temp fix until I got a new motor..lol
I would unplug the battery overnight and let the computer relearn itself. Hopefully it will work for you.
Had the same problem with a BBK on my 01 Cobra. After much work and talk with BBK I discovered the blades of the throttle body are too large for the intake. The blades of the throttle body were getting hung on the inside of the intake allowing too much air and increasingthe idle. I had the intake ports bored to match the size of the blades on the throttle body and it fixed the problem.
The tps has to be within a certain voltage when you put it back in. I think its .98-1.0 something like that.
This is on the 5.0L fox bodies where it's adjustable. If there is a problem with the voltage that would mean a computer malfunction where it has learned a diff curve because of too much flow.
