Just recently my scoob has started to idle roughly , every 4-10 seconds the engine seems to lurch as if missing a beat yet when on boost it seems fine.
Also it now starts after 5 secs of turning the key wheres before it always started first time, the cold start issue started after i had a remap, Coincidence?

Any idea's on what this could be and how to check some things?


Thx Andy
