ok i dropped a 1995 ls motor into a hatch about a week ago and its not running right and i cant figure out whats wrong with it. the car starts and drives but has NO power at all, when it idles it seems to be fine but when i rev it up it sound like its choking or something i think its running really rich, the compression is around 150psi in all 4 cylinders, the motor and everything is from a 1995 integra but the head is from a 1992 could that be the problem? I've changed the fuel pump, injectors, fuel filter, map sensor, distributor, spark plugs and wires, anybody has an idea what could be wrong?
