1990 YJ with 2.5 liter - Throttle Position Sensor

I'm replacing my TPS and was wondering if they're basically preset when you buy them? Any adjustments needed?

Yes they need to be adjusted. You need a meter to set the sensor. You can find the info in the service manual. There is a pdf of the manual link you can find by searching the forum.I would do the adjustment check on the ais and the wot as well.
