Re: How to adjust (1990CORVETTE)
I don't know if yours is adjustable. If it is one of the adjustable ones, look in the C4 tech tips under How to adjust your early TPS/idle speed.
If it is not an adjustable one, then you don't need to adjust it, the computer does the adjustments for you. Do you have an idle problem, that is usually the IAC motor.

Re: How to adjust (1990CORVETTE)
I don't believe its adjustable on a 1990. I know its not on a 91. Prior years had slotted holes where the TPS mounts so that you could rotate the unit for adjustment. 1991s do not have these slotted holes and I don't believe 90 did either. I've read on here that some have elongated the bolt holes for adjustment purposes, but I've never touched mine and have never had a problem

Re: How to adjust (vinnies87)
No its NOT adjustable!! Trust me, I just went down that road a week ago. Set base idle w/ IAC extended & unplugged & then after hooking volt meter to the TPS found that the holes are NOT slotted.

Re: (scorp508)
Easiest way to tell if it is adjustable is to just look at the sensor. Are there elongated slots where the screws are or not? Yes is adjustable.
