Ok, maybe I'm being overly paranoid, but I've noticed a new noise, besides the lifter tick that the dealer still hasn't fixed. When I'm putting along at part throttle, or I'm at part throttle and the engine starts to bog down cause the torque converter stays in lock up to long, I get a high pitched squealing or whistling noise. It sounds exactly like when your wear tabs on your brake pads start dragging on the rotor. It only seems to be throttle position or engine load dependant. At first I thought maybe it was a vacuum leak, but I don't hear it at idle or on deceleration, times when vacuum is highest. I was thinking maybe the throttle blade is positioned just right under these conditions that the air moving over it is making the whistling noise. Anyone else experience this.
