First thing check fluid level ...engine warm and running
slip through p to 1 and back again a couple of times, then put in p and check level ...engine still running..
fluid colour should be red and not smelling burnt.

Have you cleaned the MAF recently?

It does sound rather more serious than that but it's worth trying.

I sometimes had this on my N reg whenit was raining.

Nothing for it but to get under and check the connection, I used grease after i cleaned it out.

I also did a MAF clean to be on the safe side, and the problem was sorted.

I would be starting here.

Jonno,
The O/D light flashing is a signal that the EECV Powertrain Control Module (PCM) has detected a fault: if there is a possibility that the drivetrain can be endangered it can also limit the power developed by the engine to protect it - possibly why the performance is poor. see http://www.fordscorpio.co.uk/odlight.htm

As Nic says, this sort of error can be caused by poor connections - have you karchered the engine bay, at all? {} There is a multiplug on the nearside of the 'box that needs to be clean and dry.

If the autobox fluid is a good red colour instead of brown and burnt smelling it may be that a solenoid is sticking - but realistically you need the Diagnostics Trouble Codes (DTCs) read - the O/D light flashing means that a code has been stored. If the autobox isn't shifting into 4th then I suspect there may be a P1761 codes at least.

Put up your location and we'll see if a member with an OBD lead can meet with you and get the codes, see http://www.fordscorpio.co.uk/obdindetail.htm.
