Hi guys,
Im in the process of selling my Golf (begrudgingly) but it has developed a misfire under load.I have replaced the plugs, coil pack,leads and MAF sensor and it ran fine.However since I replaced these the car has been off the road for a few months so it hasn't been driven until a buyer test drove it yesterday.The eml light came on also.One problem I thought was that the fuel in the tank has been in there for the past 6 months,could this cause a problem? It's not using water so have rule out a head gasket issue.Any ideas?
