I need a vacuum hose diagram for 2000 Chevy S10 2.2 from the top of the Intake Manifold

Rubber, nylon, hoses, tubing, under the hood. Vacuum is from the intake manifold. There should be a vacuum diagram under the hood.

Hears the deal Chevy really dosn't use vacuum for engine control it is more important for the AT transmission shifting .
You have main lines 1 goes to the vacuum booster control unit for the power brakes another goes to the PCV valve and depending on what you have for small lines going to vacuum reservoirs
I would look at the MAP sensor Manifold absolute pressure .
All vacuum comes off the intake manifold its the draw of air the engine needs to run .If the Map is bad you will have A LOT of of problems with how that engine runs ,It plugs in to the intake manifold 3 wire about 75 dollars maybe slightly less its a good place to start .

I found lots of info for you, hope it helps, you will probably like the last one the best:

Sorry I don't have the diagram, but I do have a diagram of the engine and component locations. Your vacuum system is fairly simple. You have a MAP sensor attached to the air cleaner. I have pasted a picture below. It has one electrical connector and one vacuum hose that goes to the intake manifold or the throttle body.
Behind the right headlight is your evap canister. This will have a hose or line running to the fuel tank. Then it will have another hose going to the purge valve. The purge valve should be close by and it has a connector plus another hose that goes to the intake manifold.
Then you have the PCV hose that goes from the PCV valve in the valve cover to the air cleaner or intake manifold. I think yours just has a hose from the air cleaner and the rest is internal.
There is one more vacuum hose, and that is the bog one that goes from the intake manifold (or throttle body--looks to me like there are a couple of vacuum ports on the back side of the throttle body, and there may be a "T" on one of the hoses) to the brake booster. It this one was off, the engine would not run, as the vacuum draw is large. Please let me know if you cannot figure it out from these instructions and provide a picture, if you can.

MAP sensor:


purge valve:

No problem. email me at [email protected] so I can you the diagrams. Please include the engine size IF you know. If not I can include several diagrams.

missing hose? connect sensor to constant intake manifold vacuum. should be a vacuum diagram somewhere under the hood

Hi
Here is the diagram of the vacuum system for your car

Vacuum

Kind regards Indy

Unless you converted a standard shift truck to automatic there should be an open leg on the vacuum hoses on top of the engine. Take off the air cleaner and look for it on the upper rear of the intake manifold. If you can't find it get a short length of hose and start the engine. Hold the hose to your ear and search the top of the engine for the sucking sound the open fitting or hose will make. If you did convert a standard shift to automatic just "T" into the existing vacuum hose and run a new line. You need straight manifold vacuum. Good Luck!

The vent is controlled by vacuum. Check the condition of the vacuum hose associated with the vent control. What is happening is when you decelerate, the intake manifold vacuum increases, and a diaphram is slightly pulled giving you air in the vent but very little. In normal condition the diaphram wont even pull. Solution is check for a vacuum leak in the vent control trace it coming from the intake manifold.

the vacuum hose should be linked from intake manifold to thebrake booster on brakes as well as to the side of the gearbox onthe vacuum canister. should any one leak there will be a misfire or no vavuum for brakes.
