I have a 2000 Malibu, I can help you out if you can give me some more info...where on the intake manifold are you referring to?

On a 2000 Chevrolet Malibu, the vacuum transmission line is typically located near the engine, running from the intake manifold to the transmission modulator. It can usually be found on the passenger side of the engine bay, connected to the vacuum source. If you have trouble locating it, consulting the vehicle's service manual or a repair guide can provide more specific details.
could be faulty plugs, wires, coils,clogged fuel filter, vacuum leaks in hoses or intake manifold,fuel injectors clogged, leaky egr vavle.
under neth intake manifold replae fuel lines while your under there.
its on the right side of the throttle body where the plenum hose goes into the intake manifold
If you have power brakes look where the large hose that goes to the brake booster connects to the engine and that is your main vacuum source.
The vacuum lines on a 2000 Chevy Silverado run between the intake manifold and multiple valves across the top of the engine. The vacuum pressure is generated by the engine's compression.

The upper intake gaskets on a 2000 Ford Windstar V6 engine are located between the upper intake manifold and the lower intake manifold. To access them, you typically need to remove the upper intake manifold, which involves disconnecting various components like the throttle body, vacuum lines, and electrical connectors. Once the upper manifold is removed, you can replace the gaskets. It's advisable to follow a repair manual for specific steps and torque specifications.
here are a few things that can cause this, bad ignition wires, or sparkplugs, dirty air filter,ignition coils faulty,fuel filter clogged,egr system, vacuum leak at plenum or intake manifold.
In a 2000 Chevrolet Malibu, the Intake Air Temperature (IAT) sensor is typically located in the intake manifold or the air intake duct. It is often found near the air filter or in the throttle body assembly. To locate it, you may need to follow the air intake tube from the air filter to the engine. Always refer to the vehicle's service manual for precise details and diagrams.
Assuming this is a 4.3L engine, the upper intake manifold gasket would be between the upper intake manifold and the lower intake manifold.
