2003 Ford Focus 78,000 miles...clacking noise2003 Ford Focus 78,000 miles...for about a week everytime I crank the car up in the morning there is a loud clacking noise..when I rev the motor it gets even louder..almost like when you need oil...My husband checked oil and all fluids. The funny...
every 2 weeks? 2003 Ford Focus has Po171 code? I have replaced spark plugs, wires, oxygen sensor, MAF...and the check engine light continues to pop back on after about 2 weeks with the same stalling effect...the only weird thing is...if I turn my air conditioner on..the car's idle will smooth...
