The linkage setup to a throttle body is very important. Whether you've got an eccentric linkage, or just a direct one to one linkage.

In some cases with big throttle bodies they have an eccentric linkage, and what that means is that as you start to apply the throttle it will open slower than you're actually putting your foot down. Then, when you get to about 3/4 throttle, it will open up quicker. That's what an eccentric linkage is, and that's what sometimes we recommend, depending on the scenario.

So there is a lot to be taken into account with a throttle body.

Another thing to look at is, when you go replacing a throttle body with an aftermarket throttle body, there may be no idle speed device on the new throttle body. Now, an idle speed device is a comfort device. You want to be able to go out in the morning, hit the key, and have it idle up to 1200 RPM. While it's warming up, it can slowly come down to normal idle as the engine warms up.

You also want the idle speed to device to "catch" the idle as you are getting off the throttle coming up to a set of lights, or coming to a stop.

Sometimes people will say to us, that they don't care about that, that they'll sit and warm the car up. That's all good and well for about the first month, until they've gotten over that initial enjoyment of the car, and then they say, it stalls when it's cold, it stalls when I pull up at a set of lights, or they have to keep the car running at 1200 RPM to keep it idling. This is not the type of feedback that we want to hear. That is why it's so important to have idle control.

That is something to take into account when buying a throttle body.
