94 z24 ecu error?

have a 94 z24

starts hard, but it acts like its not getting enough fuel

runs fine afterwards.. but

ets and abs lights both come solid on
airbag light flashes on occasion
airbag light will flash under excel
sometimes wont shift properly
but the trans is fine
suggestions??? how do i do a ecu reset on this car

so im reading things about the IAT going bad? i didt put a aftermarket intake on, and have moved it around some, could a bad IAT really cause such a massive failure?

Sounds like your whole computer is just shot to hell, also possibly some severe wiring problem.
