different idle after camshaft/rocker arms replacement?

[daveisconfused]

so about a year ago a rocker arm broke on my car so i got all of them replaced AND i needed a new camshaft($$$). after it was finished at the shop, since then ive noticed that it doesnt idle as nicely as it used to. the RPMs dont fluctuate at all on the dash but i can hear and feel that the car is running kind of lean. what could be causing this??

This could be most anything, from an intake leak to cam timing being a tooth off. Figuring out what the problem is will be a process of elimination.
