Has anyone any thoughts on a 1.6 Mazda MX5 which occasionally misfires when restarted from hot and will not clear until a few miles have passed and then runs normally. It is fine from cold.
I imagine it will have cooked the "cat".

Thanks

My son had a bit of a missfire on his.(1998 1,6). He replaced the HT leads and the missfire disapeared. There is more on this forum about it if you do a forum search (right under where you log in / out). Apparently the advice is to replace them after about 30k miles, his had 36k on it.

Thanks. Now you mention it we did have HT leads replaced on an earlier car at about this mileage.

I had a similar problem, advice given on this forum was to replace the HT leads, which was 100% correct. New set cost around £20 from MX5 parts, who give very good service.

We have had excellent service from MX5 parts as well, right parts, good delivery. The HT leads were bought a couple of weeks ago. Ordered Tuesday evening, arrived Thursday post (£24.99 I think)

Hi,
the most common cause of misfire on the MX5 is faulty OEM plug leads you will find loads of help at www.mx5ocforum.co.uk
