[radiokid]

I posted this a while back but due to large influx of new Titan owners, thought I would run it again. I have a buzz from somewhere in front of me to the left possibly about the middle of the dash and somewhere underneath. It has been with me for 4-5 months. It is only present when the motor passes thru 1700. So I hear it briefly when accelerating and again at exactly 66 mph. The truck, well my truck anyway becomes very resonant(exhaust) at 1700 rpm. this in turn generates a sympathetic buzz somwhere inside the dash. I can play this buzz like an instrument. 65 mph...no buzz, 67 mph no buzz but hold it at 66mph and let the exhaust bellow and buzz city.

Needless to say I have pushed on all exposed surfaces and whatever I can reach underneath while holding it at 66mph (tricky) to try to isolate where its coming from. Even pulled the radio cowling and the defroster grate and tweeter cover I demonstrated it to the service writer and he was amazed.It goes in tomorrow for the 3rd time and I will be amazed if they can even find it because its so intermittant.

Anyone else or am I all alone here.
