Hey guys, Tried a search but weren't actually sure what to search for. It developed a month or so back when it rained a lot. I'll try and describe the issue. When cold and wet the engine will jerk and cause the whole car to bump/rock/vibrate. Extremely sluggish as well in any gear. Sounds rather rough as well. Had the AA out once but typically when at temp it goes away so they couldn't diagnose it. He said perhaps dirty fuel (ruled that one out), Cat (but replaced that 8000 miles ago), possibly a misfire? I've booked it into a full service on monday. Oh its a 1.4 cool/s Does it sound like a misfire? Drives fine when at temp.
