Engine Mechanical problem
2003 Ford Ranger 6 cyl Two Wheel Drive Automatic 61,000 miles
Problem started will driving a round trip 1000 mile vacation. After about 700 miles of highway driving I noticed a sqealing noise will driving. Then the check engine light flashed, and I pulled over. After letting the car sit for a while, I started the engine up again and the check engine light came on and stayed on. The squeal gets higher in pitch the more the gas pedal is pressed down and eventually disappears. However if hard acceleration is needed to get up a hill, the check engine light begins to flash. I took the truck to Autozone where the diagnostic test resulted in PO304, PO305, and PO306. Ive gotten new spark plugs and I am waiting for the engine to cool down before changing them out. Anyone know what the problem could be? I would appreciate it a lot.
