HI. Hope someone can help.
I recently had a problem with my idle speed, (intermittantly) so i replaced plugs and leads, and then found what i thought was the solution, the Idle valve, got a new one and straight away after the car idles better when parked but when driving at low speed (not tried it fast yet) it revs up and down in a pulsing throbbing type way.
Any ideas please as im off to cornwall in 2days time Arghhhhh
