the 0605 is a KAM code, Keep Alive Memory, and usually comes from having a chip or programmer installed. codes will stay until you clear them so if you haven't, they will continue to appear.

Chip has been removed for about a month. If I clear the code and then run another KOEO test, it is the first to pop up?

What code reader are you using? Maybe it's the reader itself that throwing the code. It's not a code that is going to set the light or hurt your running and most likely never cause a problem.

I agree that it shouldnt hurt running, but I am getting the p1316, on occasion as well, and I have new harnesses with 50 cent mods, new injectors, so I am trying to find out if my rough running is PCM related or IDM related?

I wonder if a loose harness some where else might be causing you codes. Check the main harnesses at the drivers firewall for tightness and possibly any moisture that may be in the plugs. The 1316 does point toward the UVC harness but if you changed them and still having issues. Was the 1316 code there before you changed out the harnesses?

I dont know, I preemptively did the 50 cent mod a couple of years ago, and when in there discover the wiring chaffed against pushrods, replaced and installed quarters, never had any other issues, once the temps come back up to suitable to work outside, wlll be looking into the wiring going to the IDM and the PCM. The main connector the 42 pin above the drivers side VC is in good shape around that area, and all the wiring that I have checked on the engine appears to be good. I have just heard "reset the code, if it comes back replace the PCM", but before I did, I wanted to investigate the wiring anyway.

IDK, the 1316 would concern me more than the other. Will the Snap on do the same test as an AE like buzz the injectors, contribution test, ect? it's possible you may have another chaffed wire, loose harness?

Yes it will do all of that, and I have, buzz, is very nice, distinct and crisp, all 8 windows up hood closed and can still hear them great. cct passes and only once in a while gives balance fault on 3(grey CPS) installed. I have had the vc's off quite a few times hoping for another chaffed wire, or a connector that backed out, but all is well.
