How is the throttle body connected to the PCM?
The throttle body is linked with a throttle body position sensor which collects information regarding the amount of air entering the intake. The sensor then transfers this information to the PCM which decides how much fuel should be mixed for an effective combustion process.
Where is the power module located on a carburetor?
The white wire coming from the throttle body unit connects to the negative side of the coil. There is a six-pin CAN Bus connector that connects the power module to the throttle body ECU. A grommet must be used if the power module is located inside the car.
What causes idle surges on a car ECM?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges.
Do you need NPT adapters for a carburetor?
You will need to install either 1/8-inch NPT or ¼-inch NPT barbed adapters into the baseplate/throttle plate of the throttle body to do this. With older cars, chances are you only need to deliver ported vacuum (versus manifold vacuum) to the distributor vacuum advance canister. Tape and secure any wires you removed from the carburetor.

Why does a Double Pumper carb bog down?
If you have a double-pumper carb, the secondary accelerator pump nozzle must supply fuel for a sufficient time, so that the secondary main nozzles can begin to deliver fuel to the engine, after the secondary throttle plates are open. Otherwise this will also cause the engine to bog.

Is the throttle body dependent on other parts?
This is carried out electronically in electronic fuel injection engine systems. In most vehicles, there is only one throttle body, with a rare exception of special, larger vehicles. The function of the throttle body is also dependent on other parts, such as the air filter.
