SOrry for late reply...

Its a pectel ecu t2 with a mountune map. The loom is escort cosworth - Boost amal valve , Water temp Sensor , Map Sensor ( another one hard to find aps 02/03), I think im may have to send off my ecu somewhere to be checked out because i was having problems with the the amal valve aswell.

The car was running fine untill i booted up the road. obviously after a good idle and warm up drive, but after full throttle the bad idle problem cam back. Initially i though it was the manifold because after 1st inspection it had warped. Got a new one , put her all back together now all this.

After speaking to few other people it has become apparent that the temp sensor MUST be exactley the same. So the fact that ive been using copy parts leads me to believe these re prob not transmitting required signal.

Original on order....ill let you know what happens.
Seems my idle control valve has also been modified and doesent have original zetec bracket. Just wanted to give it a clean - was surging - icv symptoms right?

Ford cannot locate the following part number y4se - 68876 - aa . This is in place of theoriginal idle control valve bracket. Its like a continuation of the metal straight on the intake valve. Basically i have undone it at the wrong point destroyed a gasket and can only seem to get this diamond shaped green gasket with a motor factor ICV , and as we know they are 80% duff parts, wheras fords supply one with the 'sunglasses' rubber type thingy..this green gasket has become the needle in the haystack.

phew...didn trealise i typed so much...
