I hope some one can help. My MX5 misfires while I am travelling between 50 and 60 miles and then kicks in again. It doesn't lose speed but loses power. Te engine light flashes and then comes on solid. The solid I am told is the cat which is now ruined due to the misfires
I have checked plugs and leads and all replaced. Has anyone got ideas as I don't want to replace cat until sorted.
Cheers.

George ?? I have been called a lot of things over the years but never George....Both coil packs are the same so its only a case of getting 1 only, fit it,if car is still the same ,refit your old one on the other pack. 086 8226506 ,ROBERT

A big thank you to Robert for supply of Cat Conv and Coil pack. Robert all worked perfect and for the first time in years I have no engine light.
