Crazy TPS Sensor
So, i went and bought a new TPS sensor last night to see if that would fix my slightly high idle and keeping the RPMs up about 1500 when i let off the throttle.
So i swapped the old for the new and all of a sudden i have a 2K idle... WTF. So i swapped the old one back in and same thing as it was doing before.
Just being curious, i letf the old one plugged in but DID NOT bolt it back up and, TAADAAA!!! It runs like a champ! How could this be?

My neighbor did... ASE Cert mechanic. And he said the voltage was reading wrong... This is my first electronically controlled vehicle. I dont know how to work on them, and im learning quickly that, i hate them. LOL

You can check voltage with the ignition on, or resistance with key off. It "sounds" like a wiring issue tho. You have to verify what is actually wrong unless you have deep pockets and just like replacing stuff.
