AU 3 Falcon misfirng only when warm

[JohnnyN]

My 2002 AU3 has developed a fault where it starts to misfire badly, but only when up to running temperature.

I've cleaned the throttle body and the sensor thing in there... next step is probably to replace the coil pack, etc.

Just wondering why it would only do this when warm?

Really bad misfire, too - sounds like an old Russian tractor, and shudders like a crapping dog's tail.

Anything else I should check before the coil pack? I've done that once before and I remember wishing many unpleasant things on the 'designer' who put the damn thing where it is!

Cheers
