My daughter's Car -
Suddenly won't go over 30 engine management light on
Stopped the car
Restarted car and whenever reached 60mph felt it was going to stall.
Previously, the other amber light came on occasionally (like a sun symbol with ! in it) and gearbox reluctant to change at times.
When I checked auto fluid level it seemed too high to me.
Taking to an honest garage who has diagnostic reader later today - any comments or advice welcomed - thanks
