TPS adjustment????
Does anyone know how or if I can adjust the Throttle Position Sensor on 91 S10 Blazer 4wd 4.3 V6?

If there is an adjustment, it would be adjusted by loosening the mounting screws and twisting the sensor.
You want it to get as close as possible to 0.5V at closed throttle and 4.5V at wide open throttle.

Is there an adjustment for the IAC as well? Reason asking, when i get on the gas, my Blazer will stutter a bit. Runs great when cruisin. I know it can be a fuel pressure problem, but the TBI was taken off and cleaned by previous owner . I was able to take IAC off by hand and I cleaned all the carbon off.Does the needle and spring need to be adjusted correctly or does it stay in a fixed location? Sorry if all these questions are getting to be too much, but I just want to be sure. Thanks for all your help!!

No adjustment for the IAC. The computer controls its positioning.
