I've been having problems with the engine management light coming on and the car not running properly.
When driving the car would judder/buck at a steady throttle and is taking longer to start than usual. The management light didn't come on at first then after a while it came on but there were no codes when I took it to my friends to read them. The only thing that would come up on the reader was N/A 01/01.
We changed the map sensor and cleaned the egr valve and also cleaned the throttle body using carb cleaner and cleared the fault code.
The problem hasn't gone away and if anything has got worse. The management light is still on and the code is still the same.
Any help gratefully appreciated.
