See thats the thing, at idle or WOT the symptom is not there. I would assume that if it is a bad coil/Sparkplug it would be more pronounced at WOT..

I did try the Throttle Body Alignment, and I thought it had fixed the issue as there was absolutely not surging. However after getting on the throttle for a few quick stoplight to stoplight runs, it came back.

Cars booked for an appointment on thursday, so if anyone can point me in a direction to talk about with the SA it would be much appreciated
