I have a similar issue that's started since a new clutch was fitted by a garage I've never used before (and won't again) as clutch failed here in Manchester away from home in Norfolk. I'm not going back as the guy tried to overcharge me and I beat him back down, I know I'll prob end up with a spanner in the works; literally!
Basically all's nice clutch side of things but there's now shed loads of what feels like drive train shunt (that lovely lurch when going on and off the throttle) that whilst always present is now really quite bad and makes me look a proper crap driver to pasengers! It can be avoided with extreme caution on the throttle, but as I say is far worse than one would expect. Any thoughts?!
