So here's the issue: engine first fires up and is rich enough to run ok for about 3 seconds then the engine goes very lean even though eq ratio is about 8.9 to 1 afr. I have no plans to leave it that rich, I did lean it out and it's worse. I haven't put my wide band in it yet, just going off of the o2's. This is a speed density tune I just started on. After it runs for about 3 to 5 minutes it runs good and smooth for a big cam that Idles at 65-70kpa. Any thoughts would be appreciated.
