2001 Mondeo 1.8 misfire

[deadslow]

Help please!

My mondeo has developed a misfire. It suffered from this last year and was cured by new plugs and leads, sweet as a nut. The misfire returned recently and the coil pack and one lead was changed, which cured the problem for a couple of weeks. Misfire now coming back. Car at 157k, currently driving 30k per year. Any theories or suggestions very much appreciated.

another lead failing?

[deadslow]

could be, I suppose. Might just change them all as a precaution.

[marcus85]

if one has failed already it isn't inconceivable that they will all fail soon. where they a decent make?

[deadslow]

stuck on by local garage, so might be el cheapo. Will do plugs/coils/leads myself and see how she goes.

yeah stick some half decent ones on and hopefully will be fine
