artscot79 Posted April 27, 2012 Share Posted April 27, 2012 hunting is normal low revs the car will optimise the emissions by continually varying the fuel and idle speed known issue most if not all mk1 do hunt slightly you cant change it do dash test if revs are between 670 and 730 when warmed up its normal below 630 idle speed control valve Quote Link to comment Share on other sites More sharing options...
