I may have your answer. After dicking around, or should I say getting dicked around by several ford dealerships <all now paying the wrath of Ford Quality Control...my old man> I hooked up with a ford engineer on loan to roush racing. He took my car into the Livonia location and came up with something that he had never seen before. After replacing the DPMF, both o2 sensors, the egr valve and sensor, the evr valve, and running a complete fuel injection maintence/cleaning, ford as well as my new mechanic still came up with the same codes as you have, same symptoms. Codes pointed to precats also. What the final problem was the coil pack, which looks like an inverted lego. It does some sort of controll of the cylinders and the firing, ya ta da, and is paired in two cylinders, 3 pairs. I had half a pair, one cylinder, not broke? or not functioning properly. I put a new coil pack on, and after 2 months of a shitty running car, I can finally enjoy my 'tour again. I actually forgot how much I love my car. Hope this helps. I will look for the schematics of the job and parts and post them. I have a 95 lx.
