Hey guys I just got my HO intake and APN exhaust manifold installed on my 90. The thing runs like a top for the most part, idle is great, sounds great running, all that. But when I accelerate it backfires really bad. At first I had the exhaust hanging off the headers so I thought maybe having absolutely NO backpressure was causing it. It seems to have the power definitely but its now mainly around 35 or I suppose the 2000 or so rpm band that it does it, right as its about to shift to OD. My question is what could be causing this. Backfiring is the result of the inproper ratio of fuel/air right? I used the 90's fuel injectors, I used the 90's TPS (and it is adjusted to .82% or so), and I used the 90's IAC, those are the only sensors I could imagine that would effect it. Oh yes, and I also used the 90's 02 sensor. Anything else you guys can think of?
Thanks in advance,
Collin
