Thread: PLEASE HELP! Codes P0102 & P0452

low input sounds like a voltage issue, do you have another pcm to swap out with and see if it stays gone with that?

I checked the fuses in the engine bay and in the car that where listed for emissions and/or maf...not sure if one of them was #25. I will do that tomorrow.

Also, I do not have another pcm to try out.

The first PCM that I got around the first of the year had issues. The EGR insufficient flow code would come on and off all the time. I sent it back for another...and after about a month of normal driving...gremlins are back. The car starts up and idles all jacked up for a couple of minutes (sounds like it wants to stall, like a 70's Camaro) and then runs fine. But the exhaust is real rich (similar problem with first pcm). When I'm driving and I let off the gas the rpms jump up and down.

Thanks for the help...any other suggestions would be great...This has been a nightmare since the first of the year...and there is another issue that I am going to post about a possible axle issue
