This has been a regular problem on the 4.2 vortec motor. Usually the Throttle Body has to be cleaned. Even with as many as 30K miles. Easy process.. When you do this you must unhook the neg battery cable to reset the PCM. They make a throttle body cleaner (different than Carb/choke cleaner). You can get it at any parts outlet. Trailvoy.com has a article describing the whole process step by step. Takes about 30 minutes. Do a search in the article section under throttle body cleaning

The relay is acting up. If you take it out (it is the only white one) bang it a couple times it will work properly.
