A little update. Turned out it was mis-firing in cylinder 1. Spark Plugs & coils for 1 & 2 changed. Also needed a new tyre yesterday & got told I had a knocking on the nearside front. Diagnoses broken/worn link. Anyway fixed today. Result--a new car!!!
Ought to be really, as in last 2 months I've shelled out for new radiator (old one was leaking) a service, MOT and another tyre in addition to above.
Just need to get the rear passenger door window working and it'll be like new, well once I get the paint scuffs on the front wings sorted
