Arosa 1.0 misfire

[arosa]

Arosa 1.0, 2000, 70000 miles has just started to misfire. Will not exceed 3000rpm, CAT smells very hot, rough idle 550-700 rpm. Any suggestions as to where I should look for a solution? Thanks

Diagnostics showed nothing. Replaced plugs and leads and it appears to have cured problem.

Do a compression test,wife's 1.0 Mpi had similar turned out to be a valve had burnt out . I think the valve was about £13 something.NIce little cars ,I borrow it all the time if I'm popping about in town so easy to park etc.
Right as rain now ,good luck with it.
