The only other weird part to this is that when the engine is cold there is no vibration in gear. But as soon as it reaches operating temp the vibration is there when in gear. I am also noticing a tough start in the morning, the engine idles very low and then the ISC kicks in and rpms come up - but not right at start up.
Yes, I believe the center support is damaged since you need to force the front mount in.
When cold, the engine would be running at a higher rpm due to the cold start feature so vibrations might be minimal but when idling speed drops, the vibrations would increase.
During cold start if the rpm does not increase immediately, it could be due to a dirty ISC. The other thing would be the valve clearances. If they are too tight, the engine would idle slightly rough and that might cause the vibrations and the
low idle at initial startup.
