The mechanics of the throttle body in no ways inhibits the amount of fuel that is delivered.

throttle body is located at intake manifold ..follow snorkle from air cleaner to where it attaches to motor ..looses hose and clean with carb cleaner there..open blades(throttle) to get behind entry good also..... fuel filter is located in tank and in line from fuel tank just in front of tank inline with fuel line...good luck

This is usually an indication of "blowback" caused by worn piston rings. How many miles on the engine? There is not a cheap solution if it is blowback.

the higher the speed the more veloctity will be pulled OUT of that cowl opening...... those rear opening cowl hoods are ment to **** air ( THE HOT AIR ) out ! not in .
Acording to the procedure.The hood is fed by the positive pressure created at the base of the windshield. The 'hood' system starts to become effective around 35+ MPH by providing good clean but more importantly, cooler air. Cowl induction systems work well if put together properly. Usually there is a air box that fits under and around the air filter assembly and seals to the hood when closed. That isolates the air filter from the hot engine air and allowing the carb or TBI to pull air while the cowl opening pushes cold air . Thats the idea.
TBI Throttle Body Injection is a very versatile, highly adaptable form of electronic controlled mechanical fuel injection. TBI provides the optimum mixture ratio of air and fuel at all stages of combustion. TBI has immediate response characteristics to constantly changing conditions and allows the engine to run with the leanest possible air / fuel mixture ratio, greatly reducing exhaust gas emissions. Because it's air / fuel mixture is so precise, based upon much more than simple engine vacuum and other mechanical metering means, TBI naturally enjoys an increase in fuel economy over a simple mechanical form of fuel introduction such as a outdated carburetor.
The TBI form of EFI is controlled by the ECM (Electronic Command Module) which controls the TBI based EFI system through all stages of operation according to data received regarding the current state of engine performance, speed, and load. The main component of this system is the TBI throttle body injector, which is mounted on top of the intake manifold, much like a carburetor. The throttle body injector is composed of two different parts; the throttle body itself, and the injector assembly. Hard to understand, isn't it? The throttle body is in fact, a large throttle valve, with a pair of linked butterfly hinged flapper valves, which are controlled by a simple mechanical linkage to the accelerator pedal. Depressing the accelerator pedal will force the throttle valve to butterfly open further and further, increasing the flow of air through the throttle valve and instructing the ECM to add more fuel, thus producing more power, faster speed, and acceleration.
Attached to the body of the TBI unit are two sensors; the TPS throttle position sensor, and the IAC idle air control assembly. The ECM uses the TPS to determine the accurate position of the throttle body valve, it's degree of cycling, and how open it is (0% to 100%). The ECM takes readings from the IAC in order to maintain a constant idle speed during normal engine operation, during all stages of power, load, and combustion.
The fuel metering assembly contains a fuel pressure regulator which dampens the pulsations and turbulence generated from the very high pressure fuel pump. Think of the FPR as a conditioner that smoothes out the flow of fuel from the outside to the inside of the fuel metering assembly. The FPR also maintains a constant, steady pressure at the injector assembly. Dual fuel injectors are mounted over the throttle valve, synchronized, and raised slightly over a venturi (narrowing radius) throat. Each injector is controlled by the ECM through an electrically initiated solenoid (switch). The precise amount of fuel delivered by each injector is varied by the amount of time that the solenoid holds the injector plunger open for operation.
A high pressure, high volume electric fuel pump is used with the TBI system. This pump is located within the fuel tank itself (which can be a PITA if you have to replace it). Once the ignition key is inserted into the ignition, and the ignition moved to the RUN or START position, the fuel pump relay instantly initiates the pump, beginning the transfer of fuel (via the pump) from the tank to the injectors. A safety relay in the system shuts the pump off after two seconds, to keep the fuel from flooding. Failure of the fuel pump relay will allow the fuel pump to operate only after four pounds of oil pressure have built up. A high capacity fuel filter, similar to an in-line variety, is located on the left side of the vehicle, at the rear of the engine.
Two common mistakes when working with the EFI system. The fuel system is pressurized. If you remove a fuel line, you could/will get a face full of fuel! The fuel pump used on the EFI system is much more powerful than that found on a carburetor installation. For this very reason, the second problem is that you cannot use a EFI fuel pump to feed a carburetor, and you cannot use a normal carburetor mechanical style fuel pump (low pressure) to feed a EFI system. In order to work on any part of the EFI system, you must first depressurize your fuel system!!!!!
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Po300 on a 2001 mitsubishi galant


Here's a link on your code.You have spent a ton of money and the dealer would of done it cheaper.I take my vehicles to dealers for oil changes,they scan and will tell me for free what is wrong since I went there for a oil and not a repair job.Then I can fix my self and not be charged for there labor.

Where is the throttle body & what does it look like ?


ALL Throttle Bodies or throttle control are bolted
to the intake manifold

Think of it as yesterdays carburater

Follow the plastic intake ducting from air filter
to the throttle body

DO NOT install ANY PARTS based on ANY CODES

It doesn't work like that

Codes ONLY point to a system NOT to what to replace

Have a 1996 Mitsubishi Galant and need intstuctions on how to replace the Idle Air Control Valve


You'll have to remove the throttle body to replace the idle air control (IAC) valve. First, disconnect the negative ground cable from the battery. Then remove the vacuum line and air duct intake. Then disconnect the IAC and throttle position sensor (TPS) electrical connections. Remove the coolant hoses that are connected to the IAC. Disconnect the throttle cable from the throttle body. Now, remove the 4 bolts that hold the throttle body to the manifold and remove. Be careful with the gasket located between the throttle body and manifold and replace it in the same position. On your clean work surface, turn the throttle body over and remove the 4 phillips head screws holding the IAC to the throttle body. Clean the parts with a dry cloth but do not use solvents on the IAC or TPS. That's it!

Rough idle and lock power


Remove the rubber tube from the air cleaner to the throttle body. Spray a can of throttle body cleaner into the intake manifold and add some injector cleaner to the tank.Also check your pcv valve is not plugged.

2001 Galant won't stay on.


Looks like gum and carbon deposits have clogged some critical parts in the engine, such as injectors.
You would need to get to the 'throttle-body'.
1. Trace the big intake-air hose to where it ends on top of the engine. This is the throttle -body.
2. Loosen the clamp that's holding the big-intake air hose. Pull off the intake air hose from the throttle-body.
3. Spray some "Throttle Body & Carburettor cleaner into the throttle-body. You could use the entire can.
4. Wipe off excess gas from the throttle-body with a piece of rag.
5. Reconnect the intake air hose, and check if the
problem has disappeared.

Idle surging chugging weird problem READ!!


hey common problem w/the 2000 galant. you may need a mirror to see this, look and or feel where your throttle body mates up to your intake manifold. it has a problem of cracking, when you have an air leak there it will run like **** and usually shut off depending on the severity. this will cause you to get the throttle position malfunction code. if that is the case instead of buying a new or used intake manifold. take the old one off, and you can actually cut it flush and weld about a 2 inch in length tube to repair the crack. well let me know how it goes.
