The air intake tube is the plastic or rubber hose that connects the air filter box to the throttle body. It should be about 3-4 inches in thickness..... The motor is relitivly easy to change. Although, you will need to remove the throttle body to change because it is located on the botton of the throttle body. Let me know if you have any problems.

RPMs jump up while driving. Foot off accelerator car will go 30mph. Difficult to stop. Changed a couple of vacuum hoses - did not solve problem.

This type of problem needs to be approached with diligent process of elimination to properly diagnose.
Check for vacuum leaks...with the engine running, spray carb cleaner at each joint and seal along the intake system and intake plenum. If there is a leak the engine idle will change as the spray is taken in through the leak.
The idle air control valve could be faulty or dirty. Remove the idle air control valve and clean the interior with carb cleaner.
There could be deposits in the thottle body causing the throttle valve to stick open. Check for free operation of the throttle valve. Clean the throttley body with throttle body safe (NOT car cleaner) cleaner by removing the intake hose, spraying the cleaner on the paper towel and cleaning the interior of the throttle body while holding the throttle butterfly plate open.
Make sure the throttle cable moves freely and that the return spring is present and working properly.
To go beyond this may require special diagnostic tools.

Location of pcv valve on 2011 camry 4cyl

It is below the egr valve close to the intake manifold below the intake air sensor, there is a tube running to it from the engine to recirculate exhaust air with fresh air, there is a clamp holding it to the air intake that you need pliers to remove, then you need to turn counter-clockwise 90 degrees to remove, do the reverse to install. to make it easier to access remove the upper intake. The pcv valve is not visible, however, you can identify it by the 3" inch long rubber hose that connects to the steel line running into the bottom of the intake. I have the part and am going to replace it soon, although Ford really makes it difficult to remove it -
pcv valve is located just under the throttle body. remove air cleaner assembly from throttle body and you will see a u shaped hose running horizontally.

Where is intake,mafsensor,iac valve,andthe idle stabilizer valve located

Assuming it is a 4-cyl, the intake is the large tube connecting the air cleaner housing to the intake manifold, which is the metal body behind and above the top of the engine. See here, p2, p40. p168

The Mass Air Flow sensor if fitted (not all Camrys had one that early) is fitted in the air intake just after the air cleaner and before the throttle body.
If you mean the Manifold Air Pressure sensor (different) that sits on the firewall flange behind the intake manifold. Follow the hose from the air intake chamber, p46
The Idle Air Control Valve is on the throttle body, see p168 and p208.

I don't know of an Idle Stabilizer Valve by that name on this engine, I think it is an alternative name for the IAC valve.

How to connect vacuum hose from/to air filter - Camry 2003

Usually you wouldn't connect a vacuum hose to the air filter, but if its a DIY job your after you would need to get the male connectors and some other hardware to do a custom job (drilling required) otherwise to have the same effect you could just connect a vacuum hose to the Intake Manifold or throttle body.

The Intake manifold usually has some spare slots for small vacuum hoses.

To locate follow the air filter box tube back to the throttle body, the throttle body, the intake is directly off this and connects to the engine. see diagram

What do I need for a tune up for my 2003 Lexus GS 300? I want to shop @ Wal-Mart for most of the content (I work there) and have the car running LOVELY lol. Please help me

To do a "Tune-up" you will need 6 spark plugs, a throttle body gasket, an air filter, an air compressor, a blow gun, a magnetic pick-up tool and a socket set with ratchet and extensions.
You must remove the intake air resonator, the #3 timing belt cover, the accelerator cable, the throttle control motor connector, the throttle position sensor connector, the accelerator pedal position sensor connector, the throttle body bracket and the throttle body. Then remove the spark plug cables and the ignition coils. You will then crack the spark plugs loose 1/4 turn and use the air compressor and blow gun to blow the debris out of the spark plug tubes so it does not enter the combustion chamber when the spark plugs are removed. Then remove the spark plugs. You will need the magnetic pick-up tool to fish the plugs out of the tubes once they are completely unscrewed.
Install new spark plugs and torque them to 13 ft.lbs (18 Nm)
Install throttle body with nw gasket. Install all other parts removed and connect all connectors.
Install intake resonator and new air filter.

Saturn 1999 sl Engine has a high idle speed. How do I find, replace, inspect IAC?

The Idle Air Control valve is located on the throttle body. If you follow the intake tube from your air filter all the way back to the intake manifold, where the intake tube connects to is the throttle body. Remove the intake tubing and you can see the throttle body.

There are two sensors on the throttle body and a vacuum line. You'll see two harnesses going to the throttle body, one is the IAC.

However, a quick diagnostic check can be done without touching the throttle body to confirm your problem. If the car has a normal idle when initially started but then rises to a higher idle and stays there BUT then if you were to shut the car off and restart it and it comes back to normal that is the Throttle Position Sensor (TPS). This is also located on the throttle body (the other sensor to the IAC). If it is the IAC it will be high and maybe fluctuate a bit.
