Right, at the throttle body more precisely. Getting codes would certainly help...
When the part is off, make sure the passageways are also clean. Get some good intake cleaner and spray it until it's clean. The pintle especially so it seals right.
It wouldn't hurt to clean the throttle body and intake valves as well, but I doubt a relationship to your problem.
The egr valve may also have some carbon issues as well as it's passageways.
