Bones Posted March 10 Report Share Posted March 10 Just had to change the battery in my journey. Yet after that happened, the throttle body apparently decided to kicked the bucket. This is a higher mileage journey, I think pushing 134k. So I got the throttle body changed, now it is revving up like it's a racecar when it it put into reverse or drive. The only way to stop that is by just lightly pressing the brake. It is only throwing one code now I believe after the throttle body was changed out. I'll have to get home and look at my obd scanner to see the code. Does anybody have any idea on what this issue might be? I'll update the post with the current code or codes knowing my luck.

5rebel9 Posted March 11 Report Share Posted March 11 (edited) Strange for such a year and even with that kind of miles on it. Sounds t me from your description that there must be a vacuum leak from one of the hoses near the TB or the seal ing "O" ring itself. I've got 3 3.6 older and all with pushing 200K miles and not had that problem with RPM's or a faulty TB. Power brake vacuum source is an electrical powered pump, don't see the posted connection you speak of to control the RPM's. Please post back what you find, and good luck!

Dean H Posted March 12 Report Share Posted March 12 (edited) There is TB relearn procedure required after you replace it. It's a function on higher level, bi-directional scan tools. Edited March 12 by Dean H Quote Link to comment Share on other sites More sharing options...
