could be a map sensor bud as it could be making it run rough. that shouldnt have happened with the headgasket - did you get a slightly thicker gasket to compensate for the skimming (they are called repair gaskets, also was it a multi layer steel gasket?)

should do a compression check before automatically assuming its the head gasket..

Could be something to do with the throttle body. When you touch the accelerator it opens a valve in the throttle body to allow air into the inlet manifold. Maybe when he takes his foot of the pedal the valve tries to close which will prevent air getting in to mix with the fuel. just a thought.
