Where is throttle pedal position switch b on your 2000 Saturn sl 2?

The throttle position sensor is on the throttle body. That's the part of the engine that controls the amount of air allowed into the engine. To find the throttle body, follow the air intake routing toward the engine. The throttle body is the part that sits on the intake manifold. To find the throttle position sensor, follow the throttle cable to the throttle body. If it helps, have someone press down and release the throttle pedal while you're looking for the throttle body/position sensor. The throttle cable causes a shaft to turn, that's the part that controls the air coming into the engine. The throttle position sensor is connected to that shaft.

Why does a 1995 dodge neon sputter at an idle?

My 1997 Neon had the same problem. I took a small nut and used silicone to attach it under the throttle. Basically giving the engine more gas. The problems stems from bad valve springs.......I have loved my neon and plan to put in a new engine in a year! Second opinion: Take it to an Auto Parts store and ask them to check and clear the codes for you, this is a free service. Most likely it is the mass air flow sensor or TPS throttle position sensor. The codes will narrow it down.

What is part load in internal combustion engine?

"Part Load" is short for partial load. "Load" is when the engine is doing work. Whatever work the engine is doing places a "load" on the engine which resists the engine's turning motion and slows the engine down so it requires more throttle to maintain speed. "Partial load" is when the engine is doing work that would stall the engine at idle, but does not require full throttle, just partial throttle. A good example would be a car traveling at highway speed or up a slight grade.

What does a performance air filter do in a car?

Your car's engine is essentially a giant air pump, combusting a mixture of fuel and air with a carefully timed spark. The more air the engine has available, the more horsepower it can make. An engine that breathes more easily will also show improvements in throttle response. Throttle response is measured by the amount of delay or hesitation that your car exhibits between when you press down on the gas pedal and when the engine responds by delivering power. Improvements in throttle response give you more "pep" in your car's acceleration.
