    Fzs running problem

    Hey been having dramas with my ski looking for help. The drama is running rough missing and lean at idle 20:1. Fuel pressure is good 55psi not dropping and have changed coils and plugs but still the same. When I pull the throttle I goes lean sometime and by letting it off the straight back on its fine. When running fine it's 11.5 wot. Any help would be great.

    Do you have a vacuum leak?

    It's a random issue? You could be getting heat soaked or even a heat soaked sensor could cause a lean idle.

    I was there and heard it, it sound just like if you were to unplug a coil and run it under load conditions.

    heat soaked can't be a possibility it didn't run long enough to get hot, plus the intercooler is a type13.

    Intercooler could be leaking water into air stream

    Yes heat soak on a sensor could be it but what sensor? Don't believe there is water in the air as it does it on the trailer
