Maybe you guys can help me out with this. it's aggravating the crap out of me. I'm throwing money at it and I need to go through the process to figure this out. My codes are 2127 and 2138. I've tried everything I can think of. it started off happening once a couple months ago, went couple weeks, then shorter, then I went on a 500 mile trip and since it does it every time I drive it. My known triggers are both, allowing it to idle to running temp and throwing, or hesitation on strong throttle in a couple spots and it throws, to hitting a vibrating series of or solid bump. What I've done so far, is had it to the dealer 3 times with one update, which didn't work, and no other positive from it. They aren't much help because I run a charger and they eventually say, probably something with the charger so I want to smack the shit out of them. The electrical pathway never gets to the charger. I replaced the PCM when I added the charger in November so I don't think that's it. I changed the clip going to the throttle body because it had a broken fastener. I changed the throttle body. I looked at the pins there and all seem to be ok. I've changed the accelerator pedal, reset the memory, backed out the tune and reflashed it, looked at the female on the APP clip and didn't see anything obvious although its a bitch to get to so I didn't spend much time or get the best of looks at it because my back is too old now to stay bent backwards that long, but I did verify that I could see good flash of metal at the females and no visible corrosion. I pushed the clip in and detached it numerous times to make sure it was seated properly. I've wiggled it running as with the other clips to see If I could throw it. along with the brackets at the pcm. I'm kind of at a loss here and looking for anyone with an epiphany to point me somewhere. I haven't checked voltage or resistance which is probably where I should've started but I foolishly thought that would be the first place the dealer would've looked. Now I'm not so sure. Any help is appreciated. I can't race or wheel like this and it sucks.
