My 2001 Expedition running hard, just started, I don't drive much and was sitting for couple weeks due to gas prices, the check engine light is NOT on but I can feeling it. when I accelerate it shakes until it gets up to speed, no misfiring of cylynders, when I get up to cuising speed on highway and OD kicks in, it's worse. I have to press gas pedal to get fuel to engine, anyone have these symptoms

sounds like a spark problem, check and make sure none of the plug wires didnt back off of the plugs, this is common because of the length of the plug sleeve on the wires...just a thought good luck

I have changed the spark plugs, all 8 coils, fuel filter and pump on my 2002 5.4 expedition. Also changed the first fuel injector because it was not firing. Check the injector and it still seems to not be firing. It is running rough and tends to hesitate more right after it shifts into its last gear. The check engine light is on and indicates that the O2 sensor is bad and reading to rich. He also stated that (?) was receiving too much air. One mechanic has told me that the O2 sensor reads bad because something is causing it to read bad and that the problem was not the sensor. Another told me that the valves were not opening and closing properly. Another told me to add Lucas to the tank. I went a step further and added to the oil when I changes the oil also. I have used mystery oil in both the tank and oil case and still on minimal improvement. Any help on this issue will be greatly appreciated, I can't keep spending money and still not fix the problem. PLEASE HELP! Thanks.
