My Sephia has 61,000 miles and untill a few day's ago Had no prob with car. My check engine light has been on for awhile but it started making a squealing noise like a cat coming from the front of the engine near the manifold it gets louder as you push the throttle. Sometimes it will not start squealing until you put it in gear and drive it. Also it has NO POWER 60 MPH is my top speed and it takes forever to gain speed while driving. The engine sounds perfect at idle and makes no noise untill you mash the gas. Transmission changes freely without no prbs. I have never heard a noise like this before it squealls but it is not a belt or lifter. And the power loss has got it sitting till i can figure this out. Any help would be more than appreciated and thank you for the time to help. I am new to kias and don't know were to begin...Thank You.... Also it is a Automatic Trans.
