I've seen this come up every now and again and I'm not really sure how to search for it. Anyway, at 3800 RPM, my car hit's a huge lean spot. The readings actually completely drop off my Autometer A/F gauge and the car usually bucks very lightly. What's up with this?!

 

3800 hesitation. The secondaries aren't comming on properly. Try re-grounding, cleaning fuel system, and maybe even rebuilding the injectors. That should help some if not then you have to figure it out.

 

Sweet, thanks for such a quick response. Maybe I should just go ahead and upgrade my secondaries to 720s.
