Hey guys
I'm new to this forum and about 2 weeks ago I bought a '77 280z 2+2 with a L28et swap. I've noticed that when I floor it, at about 3000rpm it backfires and stops accelarating.. From what I can find in this forum it seems it's either an ecu issue or an afm issue.
Do you guys have any ideas to add?
Thanks ahead of time.
