15quid i got it for
put it on over the weekend and it still was revin away on its own.
so i had a good look around the engine and found
to wires leadin to nowhere they had been snapped
several times by looks of it
then i saw a plug with no wires on it so i put the snapped wires
on the plug n hey presto no revin so that was the prob
so i am gonna nab a plug off the polo n fix them in properly
coz it wastes petrol revin all the time
so i got 2 stabilizer valves now both work fine aswell
