hi all.
sometimes when i get in and start my car the clocks do the dance? and i loose all my fuel data from the computer does anyone know what causes this and how i can fix it?
also it runs great from cld but when it warms up it goes sluggish and slow i have bought an OBD system (using scantool.net) and it shows no fault codes but hw do i change some settings on the ECU?
cheers

The Clocks dancing on start up a sure sign that your battery is about to give up...
The scorpio takes a LOT of power to get it started and if it falls below a certain voltage then the whole system resets..... The ecu will go into learn mode after a reset which is MOST likely why it feels sluggish.
Get a NEW 75amph battery and then see after a few days if it gets any better...
Details of how to change the battery are HERE

I must agree with Snoopy on this one, i had the same problem a few months ago.
Got a new battery and the problem was gone.

I'll just add to the above, in that the same can happen if despite being good, it happens to be a bit low on its charge. Mine does it if the car has been left for some time unused.

thanks for all the advice but the battery is only 6 months old and the car is used everyday it is fully charged.
This only happens somtimes even after a long trip??
could it be some kind of short?

OK Yo say the battery is fully charged and it only happens after a LONG run.... Suggest you check the output of the alternator then make sure it IS charging correctly.
You could also check the voltage of the battery when cranking by going into the dash board diagnostics ..... by holding the reset button for 10 secs then pressing until you get to voltage ... kae a not of the voltages when NO load.... when cranking anf when the engine is running .
But JUST becasue the battery is 6mths old does NOT mean it could not be a fault...
What size is the battery .. is it a BIG one ( capacity )
the dash reset is HEReif you need it
