90 Si w/ZC intermittent code 16.
 

I've been getting these very random code 16 (fuel injector) codes on my ECU lately. When it happens the engine bogs for about 1/4 second and then the CEL light pops on. It only seems to occur while driving in the city with the engine at normal operating temperature. To the best of my knowledge it's occurring between 2500-3000rpm. When I get home I reset the ECU and try to recreate the problem, however all attempts have failed.

I've troubleshooted the injectors and the injector resistor box. Everything is cool with them. Do you think it could be an ECU issue? I've been successfully running the PM6 since May without a hitch.

might be a wiring problem, try changing the injector resistor regardless and see if it acts up and strats working again

I'll check my wiring again and then give that a shot. Thanks

code 16 refers to injectors but it is actually a fuel supply problem.

check ur main fuel relay it maybe had an intermetent lose contact problem. you can open it and check the circit board most likely the solders are cracked that can create a false code. you can try to resolder it but the best if you can put a new one from honda.
