A bad throttle body may cause stalling in the vehicle, misfiring, electrical problems, high or poor idle, and improper throttle stop. Issues such as grime and dirt deposits or vacuum leaks can also cause problems to the throttle body. Below, you will find some further information about throttle body diagnostics.
Where are the throttle bodies located in a car?
Both types of throttle body assemblies (mechanical and electronic) are located between the engine air filter and intake manifold. Most cars use just one throttle body, though some engines (usually those with twin turbochargers) use two throttle bodies.
Can a bad throttle body cause strange fuel mixture?

In the case of the throttle body (and related sensor), when this happens it causes false information to be relayed to the car’s computer, resulting in faulty corrections to the air-fuel mixture.
Both types of throttle body assemblies (mechanical and electronic) are located between the engine air filter and intake manifold. Most cars use just one throttle body, though some engines (usually those with twin turbochargers) use two throttle bodies.
How does the electronically control throttle body work?
This is a video on how the electronically control throttle body works. Also, some of the common parts that fail and how they fail. A DC motor drives a toothed plastic gear, that in turn drives the throttle plate gear. A potentiometer sits on the throttle gear and returns signals to the computer through the sweeps on TB cover.
Is there a warranty on a Ford throttle body?
Now there is no mention that this could happen on the FORD site, and I am at 90000 miles with the catalytic converter warranty for up to 80000 miles.
