misfire on 2.0 16v

i have an annoying misfire on my 96 2.0 16v ultima estate.the tickover is erratic,particularly when cold,and it coughs and splutters below about 3000 rpm.
if i put my foot down at low rpm it will accelerate very slowly until the 3000 mark,then take off like the proverbial scalded cat !
iv'e cleaned out the m.a.f. thingy with injector cleaner,but to no avail..............any thoughts,
cheers,john.

hi there
sounds like it could be an air leak at the egr or a blocked cat. have the 2 rubber pipes came off the egr pipework. they're sticking out of the exhaust heatshield?

They poke out the front of the exhaust heat shield. Two stainless steel pipes with rubber pipes going to a unit on the inner wing. All visible from under the hood (bonnet?). Check them for holes or splits.
Also part of the EGR system is a mushroom shaped device at the rear/right of the engine,there should be a rubber pipe coming from this,check it hasnt been pulled off.
I would seriously consider very careful examination of ALL the wiring associated with the ignition system.Check it for missing and flaking primary insulation. Especially under the top cover,where the coils/spark plugs live.

Sprog,
The DOHC engines are prone to a misfire caused by the insulation breaking down on the Ignition circuit. This is called the Fuel Cut-off Loom, and is dealt with on http://www.fordscorpio.co.uk/dohcloom.htm
Try that first.
