Have been running my car with the engine malfunction light on for around 2 years,orginally when the light came on i took it to my local garage who found the fault code and messed around with the plugs however within 2 weeks the light was back on,put reddex in my engine every so often and generally it runs fine,there is a slight misfire but i have done plenty of mileage with it.Does anyone have any experience as to why the malfunction light is constantly on but the car runs ok or has anyone else had the same problem?
Cheers in advance
