Im having idle speed problems on my 16v. The car idles fine untill i give it some "loud pedal" (as my mate would say), ie. full throttle over 4500rpm. Then the idle sits at around 1500rpm and will not come down unless i restart the engine.
Thing is about 1/2 an hour before this started my speedo cable broke. The speedo as far as i can see is completly mechanical and shouldnt effect anything engine management wise, unless theres some sort of speed sensor somewhere. Cant see it having one though as theres no fuel computer or anything.
Anyone got any ideas or has anyone had similar problems
