VZ SV6 Missing at Idle

[JoeR]

Hope some one can help. My SV6 has erradic but servere missing at idle - It's more frequent during warm weather but it doesn't appear to missing when driving or if I increase the revs up above 900RPM.

I've had it on the analyser which did not provide a report even though the missing was happening, also tried changing one of the coil sets which seemed to clear the problem for a short time but it came back after 1 week.

The miss is quite severe it jolts the car, and all the passangers can feel it. It's feels like the engine has turned of for a millisecond.

Not sure what u mean by missing but my old car had a similar problem and it was one of the spark plug leads shorting out on the motor the insulation had been melted off if that helps.
