Guest brownd95 Posted July 8, 2012 Share Posted July 8, 2012 Hi everyone, Ive had a problem with my car for some time , misfire on cyclinder 3. vw bora 1.6 16v x reg aus engine Used to always be from a cold start within a few minutes at idle at traffic lights. -changed coil pack, ht leads, spark plugs, all lambda sensors, Still continued to see the same problem ( lucky ive got a code reader) Then, I tried Super petrol RON99 and since then it has not misfired once:) Does anyone know why this could be?? 6 months of trying different things and just using better fuel sorts it??? If anyone has got any clues please reply, cheers, Link to comment Share on other sites More sharing options...

Rupert_Baehr Posted July 8, 2012 Share Posted July 8, 2012 Which fuel do the manufacturers recommend? When they recommended that fuel, did the fuel their customers were likely to buy contain ethanol? Link to comment Share on other sites More sharing options...

Guest brownd95 Posted July 8, 2012 Share Posted July 8, 2012 The manufacturers recommend RON 95 as a minimum. Its only a 1.6 Bora Link to comment Share on other sites More sharing options...

Aleksandr Posted July 8, 2012 Share Posted July 8, 2012 Filthy valves? Coke on the cylinder head or piston crown? Tracking on your distributor? Faulty code reader? Link to comment Share on other sites More sharing options...
