Yeh basically, parked up at college yesterday and sat with the engine running for a little bit as i was only in there to pick up a mate. About 30 seconds after i had stopped and was at standstill, the car lurched a tiny bit (almost like a slightly off gear change but less) and the car made a noise as though the engine had started again...although it was already running!? Now it feel a bit heavier at least on the throttle, so when driving it just feels like there's more dragging it down or something...? Haven't checked it out yet and i wasn't doing anything, literally just sat in the seat...what could it be!?! Ghosts? Nah serisouly?
