Time after time we see these codes
it a vacuum leak
check or replace intake manifold gasket make sure if you do that the gaskets around the bolts are new too
and also you can have a smoke test done
i thing if you can have it smoke tested 1st you will save your self a lot of B/S & $$

A smoke test is when you force smoke into the intake or fuel system to help determine where you may have vacuum leaks. Where you see smoke leaking out you have an area to repair. The smoke test is very sensitive and can find the smallest leaks. Some shops charge as litle as 50.00 to do the test.
