Anyone has a slight resonance or vibration at 2k rpm's? I am trying to track it down. It is in the engine/exhaust. It does it revving in neutral stopped, as well as under load in any gear. Car is completely stock 2001 with 34k. Exhaust seems in order no loose clamps or rubbing. It is fine at 1900rpms and 2200rpms. Any thoughts? Power steering pump seems ok.
