Vacume leak detection (how can I do it)
I was wondering if there is a good way to track down a vacume leak. I've heard that you can use starter fluid to spray lightly around the hoses and if the idle goes up there may be a vacume leak. Does anyone have any other sugestions about how to do this . I am having a little problem with a slightly higher idle than what I think is normal. It is running around 12-1500 even after it warms up . I have swaped the IAC with a Junk yard one and that the next day later made it worse then I swapped it back and it brought it back down to 12-1500 . I havent tried the TB cleaner yet but may do that soon .

You can buy new lines from napa. There are two main pieces for $20 each. And then the small fitting and line that comes off the back of the valve cover is about $10. These are the part #s
First turn ur jeep on then take a propane tourch and turn the gas on, dont light it. Just pass the tourch over all of the vacum lines. When you hear the engine rev that is where your leak will be.
Hope this helps
