06 gt convertible feels shaky cruising
I have a stock 06 gt convertible 5 speed. When I'm cruising with my foot on the gas it feels fine but when I let off the throttle the car shifts slightly. every time i'm on then off the throttle it feels like the rear is shifting slightly and causing the car to shift. More noticable at higher speeds. Everything looks fine in the suspension, motor mounts and drive shaft. Never been in an accident, does have 160,000 miles. It's driving me crazy. Tried putting it on the lift and have someone simulate driving but I don't notice anything. Any ideas?
