i have a 96 contour with 160,000 miles on it and it has an engine code saying that bank 1 is running too lean. i cant seem to figure out what the problem is. also now in the morning when i start the vehicle up and get ready to leave for work i accelerate and then it boggs out in first second and third gear. it seems like its just falling on its face. also now on the freeway the car seems to cut out at 90 mph when before i could do 115 mph.
Optional Information:
1996 Ford contour 2.0 dohc
Already Tried:
i changed o2 sensors and checked the plugs and wires. also checked for vacuum leaks and didnt find any./p>
