Hello Zilvia,
I have a '92 s13 with a KaDe, 126k, Catback, and a no name intake cone.
Last week after a short drive down the street to the store, i turned the car on and it had a bad misfire. I drove home and tried to diagnose the problem, but im stumped.
It misfired hella bad, and i can smell raw fuel out of the exhaust. i replaced the #2 injector [old injector read 0 ohms] And Spark Plugs [old plugs covered in gas] but it didnt help the problem. It idled better, But didnt fix the misfire.
I have to open the throttle while cranking for it to start, when doing so, the intake backfires.
I tried adjusting timing, removing the hose from the intake to the black box, replacing plugs, replaceing bad injector, and cleaning my cap and rotor. i Checked the ECU and it threw code "21: +Ignition Signal Cuircuit" Im Thinkin its my ignition transistor chip next to the coil, but i dont have any spares. My friend said i might have to replace the head, or machine it. I dont have funding for that. :(
Any Suggestions??
