hi there

have a read of.....
http://www.fordscorpio.co.uk/homediag.htm

and for the codes
http://www.fordscorpio.co.uk/codes.htm

both are pointing to the bank 1 upstream lambda sensor being faulty. check the wiring, clear the error code and see if it returns. how's the bank 1 Long Term Fuel Trims?

Hi Andy,

I've no idea how you're getting on with your problem but Dart (Neil) may be looking to borrow the lead next so I've suggested that he contacts you to become next on the mailing list.

Ron.

Hopalong,
The Codes clearly show a problem with the HO2S11 sensor - (pre-cat, drivers side on the 24V).

The HO2S sensors are discussed in detail in http://www.fordscorpio.co.uk/ho2smonitor.htm

P0131 showed that for a time the HO2S11 returned a negative voltage - the Characteristic Shift Down. The same period probably also generated the other code, P1131 at the same time. If an HO2S sensor ever does show a negative value like this, the body has cracked or it is contaminated, so you will need to replace it.
