90 GMC 7.4L TPS Adjustment
Is there any kind of adjustment necessary after replacing a Throttle Position Sensor (TPS) on a 1990 GMC Sierra with a 7.4L TBI? The TPS doesn't appear to be adjustable but the insert in the box gives adjustment instructions.

If the mounting are of the tps is slotted then there is an adjustment.

Re: 90 GMC 7.4L TPS Adjustment
There are no slots, just the holes for the mounting screws. So I think I'm safe. Thanks.
