So about 3 weeks ago I was having a major problem with my cobalt, it kept going into limp mode and ENG PWR Reduced would flash up on the DIC and I would get numorous check engine lights for both the PCM and Throttle body. So i first replaced the throttle body and reflashed the PCM, which deff helped out the idle surging but 2 days later it went back into that mode and shut down on me while just driving down the road. I was able to scan the CEL and it was related to a MAP sensor. I replaced the MAP sensor and what do you know its fixed. I also had to remove the P0068 code from the PCM because that was making it go into limp mode as well. If any of you are having the same issues I would start with a MAP sensor.

Yah, I saw that alot of people were having the problem and not just cobalts, like alot of GM cars but no one had a real answer to fix it other than throw parts at it
