I would. It costs about $10. Let your engine warm up and leave it running. Then pull off the intake tube and pour it directly into your throttle body. Just make sure to do it slowly and not let the jeep die. Then once you pour in about 1/3 of the bottle turn off the engine and let it sit for 5-10 minutes. Then when you start it up it will burn off all the carbon. Tack it up a bit for a few minutes then drive it around town like you stole it to burn off the carbon diposits.
It produces enough smoke to hide a tank, lol. I took a video of my jeep when i did it: http://youtube.com/watch?v=fwlgjOOl45E
(back when it wasnt lifted
If you do kill it when pouring it into the throttle body, wait 5 minutes then start it up and then tack it up.
