Vibration dispeared in cold weather??
So I had this vibration that I shared with you guys few months ago, I realized now that it disappeared as the weather got colder, and same thing when I bought the car last year it was winter time and I didn't feel it when I test drove it, but in warm weather it showed up, feel it around 1500 rpm while driving or in park, it's rpm related and feel it in the steering wheel, I replaced the plugs and wires, my mechanic checked the engine mounts with no issues, from his research and mine we were thinking either the harmonic balancer or the torque converter.
But the question is, what kind of vibration that will be gone in cold weather and get worse in warm weather?? Any ideas??
Thanks in advance
