[QUOTE="Chris, post: 420117, member: 1"] The throttle body in your Jeep Wrangler controls the air to fuel mixture. The dirtier it gets, the more constricting it becomes. A dirty throttle body will affect your throttle response. You can also diagnose a dirty throttle body by how rough your Jeep is idling, again, because of how constricting the dirt and debris is. Cleaning it solves all of these problems almost immediately. You will need to remove a few components to clean it, but the results are well worth the time you will invest in it. Read on to learn how you can clean your Jeep Wrangler's throttle body. [ATTACH=full]112966[/ATTACH] Figure 1. Throttle body. [ATTACH=full]112967[/ATTACH] [B]Materials Needed[/B] [LIST] [*]Wrench [*]Torx screwdriver [*]Flat head screwdriver [*]Throttle body cleaner [/LIST] [SIZE=18px][B]Step 1 – Disconnect battery[/B][/SIZE] Disconnect the negative (black) battery cable.

[SIZE=18px][B]Step 2 – Remove intake tube[/B][/SIZE] To reveal the throttle body, you will need to remove the intake tube attached to it. First, remove the temperature sensor by sliding the red tab back, and then pulling it out. Then, use your screwdriver to loosen the screw on the clamp around the intake tube attaching it to the throttle body and remove the intake tube. You can either push it aside now, or you can loosen the screw on the other side by the air box and remove the tube completely out of the way. [ATTACH=full]112969[/ATTACH] Figure 3.
