Answer was :
It could be any number of things. from a vacuum leak to a throttle plate that is carboned up. You will need a scan tool to see what is going on with the fuel trim "delivery" from the computer depending on what the fuel trim #'s are will head you in the direction you need to go. My gut feeling is a vacuum leak or maybe you did bend something if you had the push rods in the wrong order when you did the engine work.
