I have a 93 Toyota Tercel, I replaced cap, rotor, plugs and wires but No.4 cylinder still misses. The plug at No.4 was black others were white, could it be the injector or timing belt as someone told me?

HI there,

The black is unburnt fuel, three reasons, poor spark, excessive fuel, low compression. You can have the ignition system tested on a oscilloscope, a compression testis a quick check, and the injector would be a suspect if the other two were ok. See how you get on.
