I had many CEL's after installing aftermarket air filters. I don't know the code, but it could be one of many different things. Try checking if your IAT(Intake Air Temperature) sensor is detached. Are you loosing power? Try resetting the computer by disconnecting the negative cable on your battery for about 5 mins or so and baby your car for next 10-15 miles so that it can relearn & adjust. Do what the other Contour member did & spray some electric solvent into your MAF & clean it out. Good Luck!!!!
