If he problems arose immediately after the t-belt was replaced it was likely installed wrong, however if the issues began after sometime, it is likely not related to the t-belt.
Have you put a timing light on it yet to see what if the timing is correct?
Any white smoke on start-up, does the exhaust smell like gas or is it sweat smelling? Loosing any coolant? If you have the beginning of a BHG, you could have rad fluid leaking into the cyls over night this would cause it to start/idle rough until the fluid was gone.
not at all. none of those issues. i did check the timing belt, and the cydl. was up all the way.
good to go. i'm leaning towards some intake or vacuum lines maybe.
