For some time now my 2002 PT Cruiser has been making a racket ... at around 2200-2500 RPMs, especially when I back off on the accelerator, such as when I'm shifting gears (standard shift). It's a buzzing noise in the engine, and I suspect it is connected with a heat shield or the manifold. (Four cylinder engine, 77,000 miles). Any ideas?
