I've wished there was a way to view the current temperature on my HomeScreen. Especially in our cold winters. Up till now the only way was with a jailbroken iPhone. Now its possible without jailbreak.
Damaged or broken motor mounts are arguably the most serious cause of engine vibration. CarsDirect.com suggests that a driver shift between drive and neutral while the vehicle is sitting still. If the vibration lessens while in neutral, the motor mounts may have sustained damage.
The majority of vibration problems are caused by the wheels or tires being out of tolerance in some way, usually because of an impact. When I go to diagnose a vibration, I always check the wheels first, then the tires, followed by alignment and suspension.
