Hey Guys,
48 hours deep into tuning and I have already ran into some issues go figure.... I recently added headers (boy how fun that was) and I figured I shall tune the Regal. So I do some maf tuning in open loop and upon the initial startup, there is some serious hesitation going on. Initial startup AFR is around 13 or so and then about 30 seconds later the AFR jumps to 17-18ish and then boggs down and stalls. After a few attempts at starting again and as the coolant temps arise, things are pretty normal besides the fact that my AFR is pretty constant at around 17. Any help would be highly appreciated. Thanks for your time and have a wonderful day
Jeremy
