190 2.3 Rattle at 800-1000rpm

Hello all, I am new to the board, and happy to be here. Lots of very interesting info. My question to start with is: My 1986 190e 2.3 has a "rattle" that is only present between 750-1000rpm. Hot or cold, it does not matter. It appears to be coming from the front of the engine, so I am guessing it to be the belt tensioner damper. Just wondering if any one has seen(heard) this before I climb under her and replace the damper and/or tensioner. I also believe this be part of my AC problem(erratic compressor speed, shutting down the compressor due to vibration). Just wanted to throw this out and get some opinions from the group. TIA.
