Of all the things with my MR2 over the yearsthe engine drone especially between 2600-3200rpm just gets on my last nerve. new front and rear engine mounts(rubber), stock exhaust though I do have urethane bushes all round. But if I let the engine idle while at speed all the drone goes away. Is there anything I can do adout it? I do not expect thecar to Lexus quiet but engine drone is getting on my last nerve. maybe I just getting old.
