EB Fairmont O2 sensor??? running lke a dog

Starts fine but it's like the choke is permanently on but wait injected could the O2 sensor be the culprit?? what should I look for and check.
Please List for me so I can attack the problem methodically. This is one area I am challenged in

From your 'choke' description I assume its running rich and idling high. Check the MAP sensor hose to see if it has come off, or if it is cracked. They normally crack where it attatches to the inlet manifold.

No sorry running rich as heck and not idling at all unless the vacuum booster hose is disconnected.

I've seen the diaphram inside the fuel pressure regulator leak and cause similar problems.

To check, take the vacuum line off your reg while the car is running and make sure there is no fuel in it.

It sound like your air flow meter senor the same problem happen to me I thought it was somthing to with the fuel side of things but it ended up being the air flow meter senor.The guy from ford said that it is usually a problem if you have a k&n filter 9 times out of 10 they only get dirty but in my case mine was ****ed if yours is ****ed they are not cheap. PS just to let you no the eec4 air flow meter senor fits the ecc5 an vice versa I no that for shore.
