I've got a 91 honda civic hatchback dx. So here is my problem... the car runs and revs up perfectly fine when it's cold but as soon as it warms up and ypu try too rev it up it bogs out as if it's getting too much air or too much fuel. The ecm light blinks 16 times constant them stops then continues to blink another 16 times and continues to do the same. I don't have a way to read the ecm code so if some one could tell me what the light code means I would apreciate it! I'm pritty sure it's the air flow sensor or what ever the hell it's called located on the intake manifold but I don't want to change out something that doesn't need to be changed! Confused:

Code 16--A problem in the fuel injector circuit.

Most likely it's the PGM-FI Main Relay that needs replacing. They are very problematic. Zillions of them have been replaced on this site.

Just to be safe, start your car and, using a mechanic's stethoscope, listen to each fuel injector to make sure they "click." If they do, focus on replacing the main relay. If an injector doesn't click, turn the ignition switch OFF, disconnect the 2P connector from the fuel injector that does not click, and measure resistance between the 2 terminals of the fuel injector. The resistance should be 10-13 ohms; if not, replace the injector.
