Did the timing belt and balance shaft belt on my 2004 Optima 2.4L and now when in Drive waiting for a stoplight it vibrates.
The vibration wasn't there until about 6 months ago, i did the belts in august 2009.
Last time i looked into the issue i had unbolted the driver side motor mount because i was already there and supported the engine with a block of wood and a jackstand, and when i put it in Drive the vibration was gone.
I suspect one of the motor mounts ( driver side ) is bad, even though i dont see any fluid leaks .
If it was the balance shaft being out of time i would think the vibration would be there all of the time .
If in Park at any RPM range it doesn't vibrate at all.
Only when in Drive at idle .
Are motor mounts going bad common on these cars?
