- 1999 Mountaineer 5.0L V8
My '99 5.0 Mountaineer has not been taking the winter too well. Recently, I've noticed the infamous "chirp". The squeaking was really loud a few weeks ago but I JUST replaced the serpentine belt and it got rid of the noise for a while but these past few days have been in the teens down to the single digits and I park outside so I'm not sure if the squeak is just the cold weather taking a toll on the old car or if it's something more serious. In addition, my fuel economy has dropped drastically (~3-4 MPG) since I noticed the chirp. This leads me to believe my Camshaft Position Sensor is on it's way out. Correct me if I'm wrong, but doesn't that sensor control fuel/air mixture to the engine?
