hey all!....thanks for all the input!!!

the engine runs perfect...it justs Vibrates a little more than normal. Balance shaft not timed properly makes the most sense, as the problem could have started right after the shop changed the timing belt, but is hard to say for sure because of the exhaust shield vibration occuring just prior to the timing belt change.

Going to ck the Balance Shaft Timing today...

thanks, again!!!and will get back to you with the results, hopefully positive.
