Need help with truck running rough

Ok so here is the story, my truck has been running great. I went down to help out another member with his truck about 45mins from me. so when I got there I disconnected my batteries, pulled the Idm, swapped it into coreys truck and fired that truck, it got it running but not well. I pulled his Idm and put it in my truck and mine seemed to run fine. I pulled 2 relays out of my truck and swapped them around in his truck to see if it made any difference, it didn't. I put all of my stuff back in my truck and headed home, the truck seemed to run rough but not horrible,,,,,,, but by the time I got home it was barely running and would hardly go 50 mph. when I got home I cleaned the negative batt terminals I had pulled, took the Idm back out and re installed, and pulled the relays back out and switched them around, (same part #'s) truck barely starts now. I got a P0196, P1111, one of which I did when I did a buzz test, but those codes are not in the tech library. So common sense says that something I messed with is now acting up. Any help is appreciated.

Re: Need help with truck running rough

I did take a wire and jump between the case and negative with no change, but I might actually run a permanent wire between the 2, I wonder if somehow I interrupted a good ground path somehow???? fml

Re: Need help with truck running rough

thanks for checking in, btw the superchips is sold so the truck has no tuning at all right now.
