Hi guys, newbie here to ask for help!! Above is playing up & very frustrating!! Started with management light & injector fault on cylinder4 replaced rail with all 4 + new coil pack plugs etc/ seemed to cure problem then spanner light shows find code replace crankshaft sensor again seems ok but today mystified as spanner appears again!!! & no start in also car park!!! Disconnected battery wait half hour bit of a splutter kanergoobut got home!! Been to several garages codes picked up & cleared but within hours back on spanner & limp mode/ done pedal test also etc etc any ideas lads as I'm spitting feathers & rely heavily on a vehicle thanks in advance ( seems no fuel when turning over as no fire) low mirage lovely car (when running) think it's mapped?
