What a b&*^%r the existing one is to get off! I found I HAD to unscrew, not just loosen, the bottom bolt (even though the metal mount is open-ended, because there was a washer and metal through-tube round the bolt that had welded itself to the mount. Second problem was my ignorance with connectors. The two main ones slip off when you push in the lug on the front to disengage them. Took me a while, as you think you perhaps should pull them away from the assembly, instead you push 'em in. The third and final connection (to the left of the engine as you face forwards) does pull off half way along the plastic mating.
Anyway, the replacement installs easily after all that and the misfiring prob solved it seems. Did this after replacing HT leads and fitting a K&N - so little Huck should be smooth as a pint of Guiness - which is what I think I'll reward myself with after spending best part of an hour trying to work out how to get the old coil pack off and 5 minutes fitting the new one!
MX5 parts superb as usual! Got a friend to order as I was away - and he liked the idea f a dedicated shop for one model of car (he does not own a Mazzy). The feedback reviews are especially useful, as they led me to the source of the problem in the first place. Thanks.
