Stylus XS. There are two Oxygen sensors.
When I start the car it runs great until it warms up then it seem rough, after driving 5 to 7 miles it starts to surge.when I try to give gas. Gets worse as I drive. When I park and idle sometimes run ok and at time is rough. I have cleaned EGR Valve, replaced and cleaned gas tank, replaced fuel pump and filter.
