Ok, so ive been having idle issue for the last 3 weeks or so. started out as just a low idle one day, then a bouncing idle and then finally stalling.
I figured it was my IAC or EGR, after hooking a smoke machine to my car to check for leaks there seemed to be a leak at the EGR...so i replaced it cause its really hard to see in there and see exactly where the smoke was coming from.
ok, replaced it. it got better, and by better i mean it just went back to a bouncing idle and no more stall.
I pulled my Unichip cause i know they had some harness issues, whatever that means im not too sure, but i thought this could be the problem.
so i pulled the unichip and its been 2 days, no weird idle and no stall.
i was wondering if any of you who had a 'bad harness' had anything similar to this.
i work on cars everyday and i know ghost problems happen, so before i blame something i cant really test i figured i run it by a few people that may have had the same issue.

I had the bad harness too. This is what Unichip sent me. I had the harness fixed by a local electronics chop. I am planning on reinstalling it this weekend. Hopefully it corrects the issues.

Cool, thanks for the info! i'm not sure if thats what's wrong tho. ill check it, but im not running rich or lean at idle, thats what is kinda throwing me for a loop.

I was running very rich at idle, and when I had the car dynoes the A/F's were spiking and dropping way too much.

yeah, im having no other issues and my a/f's are good and my vac. is good. It honestly just felt like a bad IAC. But, i cant even get it to act up a little with the unichip out.
le sigh.
i really with there was a different PnP for the MSP
