I have an odd problem/annoyance that's developed lately: I get excessive engine noise from 1500-1800rpm, but ONLY in that range. It seems to be a very low resonating frequency, like loud bass buzzes through a car trunk. It bothers me because that's essentially the rev range I use at every launch of the car, so I hear it a lot around town. It's loud enough for friends to notice.
I visually inspected the exhaust system with a friend revving the engine in that range, and couldn't find any leaks or rattles. I suspect motor mounts, maybe? The front is cracked, that I'm sure of.
Any thoughts?
