Strong vibration off idle

[m1nd64m3]

Car is a 6bolt in a 2g auto with no balance shafts. When I give it throttle it has a strong vibration. The vibration is worse when the car is in motion than when revving it in neutral or park. This problem just started today and i think i have been driving on it all day without thinking much of it till now. My pocketlogger shows pretty high timing advance, like 10 at idle and around 22 at very low throttle. My intake cam gear also wobbles slightly which i just noticed today. Trans shifts fine and has never gave me any trouble so I dont think that is it. what could cause this weird vibration?

Things I think it could be are maybe skipped teeth on timing belt, loose flexplate bolts, loose torque converter bolts, or an oiling problem. If anyone has experienced any of these problems what where some of the symptoms of the problems? were they similar to what I describe?

For my vibration it is always under deceleration when it has been shifted into neutral and coasting. And it is always worse in the rain... It turned out to be my U joints on my driveshaft.

check ## axles

I was looking at it last night and when I was holding the brake and giving it some gas it was still shaking so that rules out axles. I am so tired of this car, I just dropped a 6 bolt in the thing like 3 weeks ago and it was running perfect and then this happens again. Things like this make me want out of the dsm game.
