Hi, My 2002 Dodge Intrepid has a 2.7 liter V6 with 250,000 miles on it. At low and mid range RPM it runs rough- stalls out sometimes, and engine light comes on and sometimes flashes. If I press accelerator to the floor the car just takes off and goes GREAT!, but anything less than full throttle it just runs really rough. Dealer can't find a problem. oxygen sensors are new, catalytic converters are new, compression on all cylinders is good, computer is new,1 coil was replaced (each cylinder has it's own coil), and injectors are new. Engine code was checked and came back as catalyst insufficiency, and 02 sensors 1 and 2, but like i said they were replaced. Please help?!
