I got an error code 45. My engine run too rich. I got black smoke on my rear bumper and i got an excessive fuel consumption. When i start it cold, my car have some difficulty to burn gaz when i accelerate and my idle go up and down. I got new spark plug, cap/rotor, spark plug wire, fuel filter, fresh valve adjustement but it still run rich. Is it the map sensor or any other sensor?

thanx

hate to tell you bro but 45 can be system too rich, or lean...
if a car is running poorly either way it can get bad MPG
