After searching I can't find anything on the noise my car is making. I bought my car 2 years ago (99 2.0 mystique) with 11,000mi now with 83,000mi over the last year there has been alot more noise coming from the front of the car. It sounds like a hole in exhaust but at also doesn't. it's while accelerating and the sound is loudest at 3,500rpm and quieter up or down from there. if i cover tail pipe I here no leaks. the noise is there every time the needle goes through that zone. It also is only while driving now when in park and reved? I did complete tune up to try and fix it, plugs, fuel-air-oil filters, but no change. please help if you can because these zetec's are buzzy to begin with but this is annoying.
thanks
