93 golf misfire - what am i missing
Ive got a 93 1.8 Golf. Its the one with an ABS engine, single point fuel
injection. Now, its got a regular misfire on number 4 cylinder. Its got new HT leads, rotor arm and dizzy cap and theres definitely a spark at the plug and the leads are in the right order. So I think 'it must be fuel then' but its a single injector. What am i missing? The only thing i can think of is that the inlet valve isnt opening correctly because of a worn cam or something?? Is this likely? Any ideas golf gurus? |

I don't know about them, but I might try replacing/rotating the spark plug. Conceivably the plug could spark in air, but have a problem under compression. Improbable, yes, but cheap and easy. Or maybe you already replaced plugs and figured that went without saying. |

Ah - forgot to mention that I already checked compression and all cylinders
were fine. |

Brilliant. you are a genius (and I should have thought of that). It was a
tiny split in the rubber joint from the brake pipe to the inlet manifold. I replaced the pipe and the motor is purring again. thanks again dave. Stewart |
