I have suffered two throttle jams. One in a Ford Sierra and one in my Mondeo.

Many years ago I was driving a back road in sussex when I happened upon 3 Ladies in fairly short skirts all clustered round a moggy minor in the middle of the road.
I stopped to see if I could help,they said that the engine went to full throttle but they managed to stop (just before I arrived).
I had a quick shufti at the engine and soon spotted that the throttle return spring had snapped at the lower attachment point,I bent the remaining end into a hook and reattached it…hey presto (temp) fixed…they were friendly and grateful…

If only my GF had not been in the car with me LOL :rolleyes:
