Throttle Body Linkage Bayswater | Fuel Injection Bayswater

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.

What different does it make if you have a dirty throttle body then a clean one?

Because My vehicle in the morning the rmp go up and down a little in you can feel some shaking,
My question is when cleaning the throttle body on a 2000 Dodge Durango 5.9 do you need to remove the tv cable or the throttle cable? This is my first time doing this if you can tell me what I need to do step by step I will really appreciate it.
do you do it with the engine off or on?

the best way to clean it is to remove it from the intake manifold. just clean everything especially the idle controle sensor. but you could clean it still on too i guess just hold the throttle body open and wipe it with a rag and some degreaser. and remove the idle sensor and clean that.
