91 CRX with DOHC ZC, backfires through intake when pressing throttle!! HELP
Been through all of the basics, cam timing, base timing, plugs, wires, distributor, and fuel pressure regulator. It does seem to run better when vacuum hose from regulator or off of throttle body is removed??? I seen similar problems in other forums, but no one had any solutions, so hopefully someone can help.
I've tripled check the tiing so I know I'm good there. My IAC motor appears slightly damaged, leaking corrosion really bad on the bottom, and the housing for the connector is crackes in several places, maybe from the motor install. My fuel pressure is Ok, at idle and under load. Could I possible be having a failed injector, or injector resistor? I'm not the greatest on diag..
