Hi All. To keep it in a nutshell, had a misfire/running problem, changed just about everything on the "spark" side of things with no effect, I unpluged the ACT sensor, the engine note changed, the running problem has gone, plug it back on, the engine note drops and it misfires when you rev it! So changed the sensor, its still the same! As soon as I unplug the sensor, it runs ok.[compared to what it was doin!]
Any ideas?
Cheers
