hi all i have a 94 discovery es 3.9 v8 with a single point gas installation. i recently had a problem with poor running which turned out to be the air hose between the air flow meter and the plenum, changed and ran great for about 10 miles. then i lost power, kept stalling and had to limp home. now it will start the revs go straight to about 1500 them almost imediately drop to about 1000 then the engine starts hunting and eventually dies. i know i need to run the hotwire diags and will do as soon as i get time, has anyone experienced this fault and if so what caused it. Finally does anybody know a trustworthy mobile mechanic in the south birmingham area with a fault code reader who could sort me out as i am realy short on time at the moment.
thanks for any help
