Question Cobalt SS/SC, P0353, P2123, P2138 and limp mode

After installing my OTTP 2.5 catback, I did some runs and pulls. I went to the Quebec city, that is 18 miles from where I live, to go see my friend and then I come back. I stoped my car. I restarted it 15 min after. Then I went to another friend just near me. Then we went to take a ride in my city, we did some pulls and all of sudden, when I was going to do another pull, the limp mode came immediatly and then I had all the codes mentionned above.

For P0353, I swaped the coil pack #2 and #3 together. So I was like maybe I'm gonna see P0352, but no, the P0353 code stays.

I have the Aeroforce Interceptor gauge so I can clear the codes when I want. When I do it, the code P2138 stays, and the other geat ereased but they come back immediatly after like 5-10 seconds.

Damn what is the problem with my car?

P2138 is for you accelerator pedal position This code will cause limp mode check the wires and connectors on the accelerator pedal if they are okay one of the two sensors may need to be replaced.
