check battery voltage and alternator output, my 4 Motion had loads of issues, including misfire and lots of fault codes, eventually the alternator gave up.
 Charged the battery overnight, fitted a new alternator and cleared the codes, scanned again, no codes and the misfire had gone too.

Hi, yes ive cleared the codes. And came back straight away. Bummer. Hope the alternator isnt on its way out. Someone said take MAF off and if it runs fine without it then its that??? does that sound right??

Not sure about the MAF, ideally you could do with a VCDS scan, I am in St Helens and have VCDS, could do a scan for you.
 Tomorrow evening or Sunday at Three Sisters

replaced the MAF with a new unit from Euro Car parts £65 inc vat. Then the damn thing started missing even more. Plugged scanner in and MISFIRE on no 3 put new coilpack in and hey presto.  ALL GOOD now THANKS ALL!!
