slk211 Posted July 16, 2013 Share Posted July 16, 2013 Hi hope someone can help I have a focus 16 zetec 2002 which revs high whether car moving or not . this just happened whilst driving there was no signs of a problem beforehand . I have read forums and checked all hoses for splits and theres none . changed icv . cleaned maf unit with electrical spray and checked spring on throttle and carpet not sticking at pedal . also when I unplug the new icv cables the revving stops but car will obviously cut out unless put foot on pedal a little . as soon as I plug new or old icv in the car over revs again . I am out if ideas . anyone help ? thanks Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted July 17, 2013 Share Posted July 17, 2013 Sounds like you might have a duff sensor (possibly Lambda) sounds like the car is reading incorrect values at the exhaust and is compensating by adding more fuel... Quote Link to comment Share on other sites More sharing options...
