Ok, I have a 90 si hatch, b16a, PW0 ecu, y1 trans, cai, exhaust. Very simple car. I've only been driving it a week or two now and I love it. It still has some issues though.
The fuel cuts out after 7K. Its not a rev limiter, its a complete fuel cut. Any ideas?
The O2 sensor isn't working, but no engine light. I even disconnected it and no code. I thought hondas valued o2 signals!? (yes, it was warmed up. Also, I unplugged the vtec noid and the engine light came on and the car went into lawnmower horsepower mode so the engine light works)
I set the idle with the screw and it idles nicely but when I disconnect the IAC, there isn't any effect. The IAC is the one behind the throttle body, right? And the BAC is behind the intake manifold? I disconnect the BAC and the idle drops a few hundred rpm. Also, there looks to be two capped coolant connections comming out of the TB that are not connected to anything. Are these necessary for the IAC to function?
The car has been running well, it just has this annoying surge once its really warmed up. I'm thinking it is vacuum/IAC related.
Thanks for any help in advance...
