Mine's gone into Sawbridgeworth's house of pain, today with a "I don't want it back 'til it's sorted" instruction. Bloody thing nearly killed me several times on the way home from Monmouthshire at the weekend; similar/same problem as previously, i.e. /major/ hesitation under acceleration, however, this time round, we get lovely big backfires, pops, farts, bangs when applying the beans. I am /sooo/ thinking about ditching it come December...
