Question about 2003 Buick Century
After replacing the intake gaskets, I find that the engine surges -- a vacuum leak(?) -- as I increase rpms and then it seems to "stumble" and will not develop full power.
Make sure the idler motor is conected and wires are free and not stuck under the intake, and also check the pcv valve lines for proper routing, also check the line going to the vacium booster for brakes, and one of the ways to find vacium leaks is by aplying brake or carburetor cleaner to the suspected area and that will change rpm when leak found
