Doug I read up on 253-7. I understand the system now. Thanks for the help.. I must be preoccupied as I should have seen this in Bentley instead of going through all this discussion using up everyones time..Ths answer is now simple. The PO had cut the 02 sensor wire and taped it up. It was connected at the firewall but cut under the body. Second of all. There is no frequency valve. This is because someone (PO) had removed it and there is a straight connector in the return fuel line at the Fuel Distributor at the exact point where the valve should be. Now what do I do? Anyone have a Frequency Valve? And do I really need it as the car is running. But since it controls the fuel amount going into the engine, repairing the system is a must. Where do i purchase the valve? And better still, what am I going to have to sell to buy one?? Thanks Max
