I'm running a Haltech Platinum Pro with the stock map for the RB20DET + tweaks for my build. When I started it this morning, the IAT was at 32F/0C (Outside temp was ~42F) and the AFRs went off the scale for my AEM gauge. I let it run for ~30 seconds then turned it off. I then did a smoke test, by hooking into a vacuum line directly behind the throttle body, and confirmed there was no leaks ( i let the smoke tester run for ~5 minutes / confirmed it was generating smoke before hand ). I then started the car again, after fixing a power steering leak.... and it seemed to be happy for ~30 seconds (was at ~11/12), but then seemingly shot back up to ~18 again. I then let the car run for a few minutes, thinking this was just cold start related, but the AFRs never came back down. I didn't let the car fully warm up, so maybe this makes sense, but I'm not sure what to do?
The AFRs, when I last ran it, were normal, but because of personal reasons I haven't been able to break in the car. It was rebuilt last year.
