IAC and TPS (or drive-by-cable throttle body)

[TXsilverado]

the bolt that holds the TPS on, you can make it a little longer and turn it till the TPS sensor reads 0...i have had to do that same thing on some f-body's

bolt? my TPS has 2 little screws holding it down to the throttle body?

so you chop off the stud that holds it in the proper position on the throttle body?

No..

there are holes in the sensor where the screw go through...make those holes that the screw go through a little bigger..like this o(smaller hole) turns into a O(bigger hole) and that allows you to turn the sensor clockwise or counter clockwise

It doesn't take much movement to change the idle voltage.
