Can't lose 43...
 

I can't lose this code 43 (fuel system) Its came on before but that was because one of the injectors was unplugged, but when I plugged the injector back in. Now it just started throwing it again and its running like shit, anyone know what it could be? this is a 91 crx converted to Multipoint, Ls swap, thats about it, but its been swapped a while, I dont know what it could be, someone has to know what the hell the problem is.. thanks -Ben

have you reset your your ECU. You may have to take it to Autozone and have them do it, It is free........Dave

You took your car to Autozone to reset the ECU????????????????

o2 sensor

of course I've reset the ecu, and about the o2 sensor, I didnt think that would cause this much of a problem, like it wont barely idle when its cold. -Ben

yes it actually is the O2 causing the fuel supply code, seen this before

Damn good info mines throwing the same code I could not figure out why.And can running race gas cause your O2 sensor to go bad?
