hello, i have a mk5 ford fiesta and every time i come to a stop i lose power, goes down too 500rpm or stalls, i have now tried it if i put in neutral and still happens. any ideas? thanks

maybe the idle control valve, however try cleaning out the throttle housing body first for any gunk. have the air and fuel filter been changed in the last year if not then do these to eliminate the obvious.

could be something as simple as plugs or leads or one of the many sensors or a vacume leak or loads of things, difficult to diagnose without looking at it.
