I just dropped in my b16a on my 90 hatch, I bought the hatch shell with the mpfi conversion done as it previously had a zc motor on it so I just went with it without folling with the ecu pins. I dropped it in and it will only start when the throttle body is all the way open and when its all the way open it will only idle at around 700 rpm. As soon as I let go a little bit of the throttle it dies. My questions are why will it only run around 700 rpm when the throttle is all the way open ? Is this a common problem? Did I over look something ? Could it be a vacuun problem ? Coukd it be a messed up sensor ? I don't know how to check codes, do I need a special scanner to do it? I dobt have the exhasut hooked up, just the header, and my o2 sensor is not wired yet, vtec is also unhooked right now. Plugs , distributor brand new , and intake manifold was dissambled and cleaned I just listed a few things that might be a factor to what's wrong with it. any help is appreciated thanks
