ok more air flow....did you change to a larger throttle body?
Anywhere from 160 to 205 HP.
Chevy says about 210hp.
About 6 to 12 hp. But that is still dependent to the type of the throttle body that you will use and with the response of the air flow to the engine. Note that oftentimes, throttle body somehow acts like a carburetor in a non-injected engine.
Throttle body spacers increase the air volume between the engine and the throttle body.
The 1993 Fleetwoods did not come with a LT1 engine. The engine is a L05, 350ci with 185 horsepower with throttle body fuel injection. The LT1 350ci with 260 horsepower was used in the 94, 95, and 96 Fleetwoods.
The throttle body spacer is a small piece of metal that is attached the back of a throttle body. It is suppose to change the airflow which can potentially give you more horsepower and better fuel economy.
The only sensors that I am aware of on the throttle body is the throttle position sensor.
The throttle body is your carburetor in some vehicles. It is located on the top of the engine.
Follow the big engine air intake tube from your engine air filter to the engine throttle body
The big rubber engine air intake tube will go from the engine air filter to the engine throttle body
Assuming this is the 4.3 engine, the throttle body would be found on top center of the engine. The air filter assembly would have to be removed to get a full view of the throttle body.
The throttle body on an engine houses the throttle, which controls the amount of fuel that enters the engine. It controls the engine's ability to maintain an idle, prevents stalling, and aids in acceleration. If the throttle body is dirty, it can cause problems with the engine running properly. During a standard service, sludge and carbon buildup out of the throttle body and off the throttle blade. The vehicle's computer is then hooked up to a special machine for an idle relearn procedure.
