440 diagnostics
I have recently purchased a 440, a P reg, 1996 petrol, 1.8 fuel injection model, which has a rough engine. It revs fine in neutral.
I changed the spark plugs to Bosch Supers and changed the HT leads. The old spark plugs were dark brown. I have cleaned the engine compartment and sprayed the electrics with Damp Start. As my Haynes manual for the 400 series (ISBN 1 85960 565 6) does not mention the diagnostics box, can anybody help? Fortunately I have an old 940 manual which gave me an idea on how to do the tests. The only plug-ins in the diagnostics box that work are 2 and 7. 7 is fine with three one second 'flashes,' but 2 just shows a continuous dull red light and pressing the test button does not do anything. Any ideas? Thank you. |
