Engine Performance problem
2001 Ford Taurus 6 cyl Front Wheel Drive Automatic 173422 miles
My engine miss fires, has terrible gas mileage, does not go up hills. I had it code tested and it said that bank 1 and 2 are running rich and cylinders 1, 2 and 3 are miss firing. The engine icon light is blinking but it was just on constantly. I have just replaced the plugs, plug wires, both upper oxygen sensors, gas cap, also added a can of heat and fuel injector cleaner to a full tank of gas. It was running ok one day then my wife ran the car thru a gas station car wash drive thru. Then it really started miss firing and chugging when in idle and while driving. What can be the problem? Thanks guys for your time. Paul.
have the same problem?
