Iirc it was high rpm. He didn’t log it, so I didn’t get a printout. I just remember the 1.6% CO at 2500rpm was the problem.And it could have been. I used to do those alot in the 80's. My race buddies would come to the station I worked at. I'd pull up a car I had in there for a tune up that I knew would pass and plug in their #'s. Happened all the time. I'm rusty on that **** now for sure, but I do remember an engine misfire will cause HI HC, so if your HC is good, then all your plugs, wires, cap, rotor all that is still good. No misfires, unless you're getting a lean misfire which IS NOT your case since it's HI CO which is in most cases, Rich AF mixture. How does your spray pattern look on the injectors? Do you know if it failed, Idle or high rpm or both??
Failing here escalates things quickly, so he’s basically hooking me up to the sniffer to help me get it figured out before the actual test. No dyno, just two speed (idle and 2500rpm).
