Mine's started doing the same thing again, so this week end I'm replacing the coil pack and leads. I'll let you know the result, if it cures mine then it may be worth a shot on yours.

Cheer's mate keep me posted

Done. And what a difference!!!... like a new car now. s**t, cramped, pain in the a** to get at spot.. but worth it for the result.
Have a look at this thread for some helpful info.

I took all the intake plastic off as well as the bottom of the air box. Just take care not to pull the oil pressure signal wire out while you've got your arm jammed under the intake manifold. I noticed I'd done it just before I put the air box etc back in thank god!!

thats the way man did u do the spark leads aswell or just coil pack? what was the condition of the coil pack when u took it out. what differance has it made to the old girl since u replaced it compared to before?
