Two issues, not sure if they are the same thing or separate. 1.) I thought I had a wheel bearing going out, a lot of road noise sounds like a wobbly wheel and front seat vibration. Had all wheels off, checked everyone thoroughly and found that one wheel was not balanced and warped the rotor: changed the rotor and brake pads. Also had new tires put on. Vibration is gone but noise is still there? Just a constant "wharp-wharp-wharp" in the wheel area that is correlated with speed of the vehicle but does not go away in turns. 2.) AC running and the engine flutters, turn AC off and it stops. Today, turned the AC off and the engine acted like it was about to die. Turned ignition off, removed key and the engine continued fluttering until it turned off. Starts back up just fine. Any thoughts?
