My van has been sputtering it will not accelerate but only when engine is cold once it warms up after about 5 minutes of driving it drives just fine… I have replaced spark plugs, wires and the coil pack… I habe also replaced both o2 sensors (thats what my check engine light is on for) and none of these have fixed my problem… I also went from getting 28 miles per gallon to now only getting 11.8… I have had my mechanic run a severe diagnostic on my vehicle and the only thing that comes up is high circuit O2 sensor. Please someone help me out ---

Have the mechanic check if the coolant temp sensor for the computer is working properly. If the computer thinks the engine is at -10 º, the engine will run rough and get lousy mileage. Tester
