Lumpy running especially noticeable at tickover.
« on: 25 August 2015, 09:33:04 »
Started yesterday. Thought it was water getting onto the coil pack which has happened before. Fault code P0650 showing. Thoughts anyone?

Mine is, too. I've put it down to a vac leak/duff lav reservoir, which I'm still trying to trace.

Have you checked the throttle body, may be clogged a bit, that can help with idle?
