What did you do to your Ranger today? (Part Deux!)

I tried wiggling on it as much as I could in that stupid position, and it seemed really tight. But I’ll keep knocking down the clowns until we find the right one.

I wasn’t able to detect the slop in mine until I pulled it and found the bushings were trashed

squirt some oil on the cam sensor top bushing.
as the shaft & bushing wear the shaft can bounce around inside the bushing.

the TPS sensor gets 5 volts as the input, needs a good ground.
several sensors get that same 5 volt input.

the purpose of the TPS sensor is to give the PCM an advance warning the throttle has been changed.
the PCM can then adjust fuel before the actual exhaust reaches the O2 sensors.

It's way more complicated than that most likely, the most used parts are the idle setting and WOT to tell it that it should be idling to get the IAC working ahead of being at idle speed and clear flood mode, there's likely a delta TPS setting for acceleration fuel and deceleration fuel and a few other things, the TPS isn't used much for fueling, mostly the rpm and MAF combined with the O2 feedback...
