I have started having a strange noise coming from the engine compartment....sounds like Ginger Baker doing a drum roll right close to passenger side windshield area, starts at about 50mph and quits about 55 or so. It started out being intermittent but is pretty regular now. Just before this started I had a check engine light warning which ended up being upstream OS sensors which I replaced with Bosch sensors. Anyone know what's going on here?

I'd greatly appreciate any suggestions or advice.

Mike
