Postscript to my earlier message:
OK so there were no T4 patrolman standing by on the road back home last Wednesday...
Before I do have the chance to have it T4 checked, I thought I would describe symptoms a bit more fully in case its a bit more obvious to those of experience or with advice to offer.
Limped home as journey down had been with possibly slight misfiring? and slight vibration and then with slight misfiring and very noticeable vibration, above say 55mph. Improved when coasting or clutch engaged. Problem has not gone away. No engine warning lights(s) showing at any time.
Took car to Halfrauds early on Saturday morning as I know one of the guys slightly, so yes they plugged in their diagnostic tool ...but said there were no faults showing. Mmmm not sure how confident I am of that...
Do you think it is engine; spark plug(s), ignition pck(s) or VIS motor
or a tyre, wheel, bearing, half-shaft issue?
The car was MOT'd three weeks ago but garage cannot take vehicle in to have a look at it for another 10 days.
Any advice gratefully received thanks
