Hi, ive gone through checking the wiring, and following the tsb.
The car must have had an Ecu fitted by Ford some time ago as a sticker says program with wds! The part numbers on the ecu and throttle body ( 2s6u dc) are the later part numbers.
Fault is still there but can take a couple of days to fail. As soon as you switch back on car is ok, so still havent been able to check 5v reference voltage at Ecu when fault occurs.
I still suspect throttle body.
Any further suggestions will be appreciated
Thanks
Joe
