With my recent V3 install there are two minor things left to sift out. Belt walking and I'm on that, and an idle surge on cold start up.
The idle will surge on cold start for the first 2 or 3 minutes of run time and then it clears itself up. I can watch the wideband o2 and here's what happens. The mixture gradually leans out (bigtime), then just at the point where it's about to stall, it shoots over tho the rich side and the idle surges back up. Like I said, 2-3 muintes it will clear up and hold steady idle at 14.5 AF. After the initial surging clears itself up, everything is fine. This never happened prior to the V3 install which included a custom tuned chip, 30lb inj and a calibrated MAF.
It's not the end of the world but if I can track it down, that would be nice. What could it be?
