P1125 and P2138, replaced pedal won't go away

[Metal Links]

About 2 weeks ago I got p2138(current) and p1125(pending), 04 GP.I replaced the gas pedal and it was fine for a few days then I changed out my battery and it started to come back. Today, while it was raining, it came on 7 times in a 6 mile drive. It seems to trigger when Im cruising between 1000-1400, it'll jump a couple hundred RPMs then fall back or if I stab the throttle.


In last two weeks I have cleaned MAF, throttle body and the throttle wire connector. Clean 3 grounds in the cabin and cleaned the green and blue(?) wire connectors under the driver side dash. About a month ago I also rewired the front driver ABS wire(was water in it) and when I cut into the lower wire loom I accidentally cut a brown and green wire, fixed with solder butt splices. Also installed a strut tower bar.

Update​;

Cleaned the connectors going to the body control unit and took off the TB and cleaned it. There was something like a pin sliding back and forth in the TB. Is that normal? Went for a drive and the CEL came on twice and idle was high, about 800 compared to mid 600s.

I saw a TSB for the IP to Body connector being corroded, where is that exactly located?

EDIT; It threw the 2nd CEL when I had cruise control on. Would it be a bad TB or 5v reference signal?

I have had the same issues but with additional codes of P2120 and P2125. I have replaced both pedal and TB with no help. I have searched the interweb for wiring diagrams and such with no luck. I have checked voltage at the pedal and have voltage at both pins that should have voltage but when the pedal is attached they read some difference. i have tried to find ground locations and also thought of a body control unit but can't find any info. So did you solve your issues?
Thanks Rick
