Having problems with your 2001 Ford Focus ?
Engine light on clicking sound from back of engine intermittent
Take the vehicle to one of these parts stores and ask the guy or gal at the register to check your engine codes. O'Reilly's, AutoZone, Advanced Auto, Napa, Carquest. They will do it for free at those stores and probably other parts stores. After that DO NOT buy any expensive parts that it names, but repost the description that they give you exactly as it is stated by the code scanner that they attached to your car. Then we will have a place to start to determine in which order to check things without wasting a ton of money. Also when we "fix" the problem, the parts store will also reset the engine light. There is not much use turning it off until its fixed though because it will just come back on. Trust me lol.
