2002 Honda S2000 4 cyl Two Wheel Drive Manual 91,000 miles
My 2002 Honda S2000 has an annoying high-pitched whistle or squeal when accelerating through about 2,500 to 3,500 RPMs. I can’t be 100% sure of the timing, but I believe it started after having the serpentine belt replaced at 90,000 miles. I took it back to the mechanic who replaced the belt and he could not pinpoint the noise. I took it to another mechanic who swore it was the catalytic converter, which I had replaced for $1,100. It did not fix the whistle. Any thoughts on how to get rid of this annoying squeal?
