OK, I'm getting to the end of my rope with this car. Got an orange wrench light the other morning when I started the car and trying to drive it ran terrible. Wasn't shifting right, big clunks stopping, etc. Took to a friend who owns a transmission shop and the code was for the throttle body. He reset it and it's worked ok since, but performance seems a little bogged down. He said I may have to replace the whole throttle body assembly which isn't a big deal if that's the case, but after speaking with the Ford guy when I was looking to order it he said often times a vacuum leak is the ultimate issue. So that brings me to my question, how do I know if it's a vacuum leak before I shell out $300 on a new throttle body? I am not familiar with the location of the vacuum lines on the explorer.

Please correct me if I'm wrong, what can go bad on a throttle body?
Unless the housing is damaged, it's just a butterfly and return spring.
Faulty throttle position sensors are fairly common. Any DTC numbers?
 






Same question here; I just cleaned my TB, and unless you smash it with a hammer, what can be wrong with it ?
 






I agree with you guys, not sure why it's recommended the whole unit be replaced as opposed to the sensor. I haven't seen much on this form but when I googled it, I came across a lot of people with a similar problem, some saying they were on their 3rd throttle body. I don't know the code that came up. I already replaced the throttle body sensor a little over a year ago.

Does anyone have any suggestions on how to check the vacuum lines so I can at least rule that out?
 






Just spray Carb or starter fluid around if the rpm changes there is your vacuum leak.
