06/10/2016 21:45:22 Dave Have you had a worn CV joint on your MGF? If so, what were the symptoms? I have some vibration that I feel through the seat of the car - not the steering wheel - the vibration remains even having swapped between two sets of wheels, so it's not a wheel balance issue. The vibration is minor at the moment, only really noticeable when the car is accelerating hard and is passing through 50mph in 3rd gear. My mechanic has checked over the rear of car - engine mounts, rear suspension, drive shafts and can't find anything other than some minor play in the CV joints and is wondering whether that is the cause.

Try it in second which should be do-able at around 5700 RPM. I should point out that this suggestion may be biased. I feel its someone else's turn to feel like a chav, having recently experienced some rather straight looks whilst fault finding my high rev missfire driving down our local urban dual carriageway at 5000 RPM in second ;)
