Welcome Visitor! Please take a few seconds and Hi,
Was my issue yesterday at one of those quick lube places just a pure coincidence, and am I on the right path to correcting the issue? The truck has a very high idle upon starting and when shifting. There is no tachometer so I can’t state definitely the specific RPMs but I am guessing them to be about 3,000 RPM.

I just moved to a northern state from a southern state 2 days ago. I took the truck to one of those quick lube places since all my tools are packed away. Oil change, rear diff change/fill, radiator flush, & fuel injector service. Upon starting the truck after the oil change it revved very high. The staff immediately shut it off and restarted it. It did the same high idle again. And again. And again. The staff then asked me if it had done that before, which I answered no, it was the first time. They came back in a few minutes suggesting it was the IAC. I agreed since I had not yet researched it so an IAC was delivered by O’Reillys, installed, and….. no change.
I drove it home like that, about 15 miles, disconnected the TPS in the garage and now I have a check engine light on . But, disconnecting the TPS seemed to fix That leads me to believe I need to change the TPS.
Was this a coincidence?
Could the staff have accidentally caused this issue?
Would reconnecting the TPS, and then disconnecting the IAC to see if the vehicle stalls prove there is no vacuum leak?
Since disconnecting the TPS appears to resolve the issue, should I just replace it, call it good, and move on?
Other info- could this be related?
About 4 weeks back the ABS light and E-brake lights were lit. The brakes were not working properly as they were prone to lock up. I figured that was due to the ABS light being lit and something was wrong with the ABS system, plus it was raining and new tires are needed. I am buying new tires today. I Googled why the dash lights were lit and learned possibly low brake fluid. Sure enough, the master cylinder was low so I topped it off, and the ABS light and E-brake light went off, and the truck started braking properly. The master cylinder is still full, and no dash lights, but just before I pulled into the quick lube the truck did not brake properly twice when coming to a stop. We then pulled into the quick lube and the issue issue popped up.
TIA
