Checked above, AFM connections seem clean, coils are tight and seated.
Car drives normal - just slightly sluggish. Even on idle sounds slightly different, and when you hit the accelerator from idle, revs come up slightly slower then normal.
The car is booked in at ASG next Thur for a general check (just brought it), but this issue has just happened overnight, and is frustrating!! - hoping iys just plugs.....
