‘95 Sierra K1500.
My drivability issues are all ironed out so now I’m in the tinkering phase. Today I checked the voltage coming out of my TPS. .8v with the throttle closed. After confirming that the voltage climbs appropriately with throttle actuation I decided to slot the TPS mounting screw holes a bit to see if I could get it closer to .5v at idle. I managed to get it down to .47v but the truck idled horribly. I was up against the clock so instead of disconnecting the battery to clear the computer I just rolled the TPS back up to its “stock” position and drove it away.
But NOW I’m wondering if I shouldn’t roll it back to read the proper idle voltage and let the computer relearn or just leave it at the .8v position.
What say ye expert types? Get it on the money or just be happy the truck is running well?
