My v6 3.0L duratec in my escape idles up and down and the engine knocks hard and loud at a cold start Almost like its stalling but then the idle jumps high then low. I have replaced the Air flow sensor, the codes say coil misfire and I replaced those twice. Still acting up and burining excessive fuel. Spark plugs, intakes etc all been replaced. Any help would be helpful.

Do a wiggle test on the wiring harness coming off the ecu, check for a broken wire in the harness, have seen this on 2 other escapes.
