it can either be a vacuum leak or maybe something isnt getting the right amount of vacuum? i think your issue is vacuum related because i had a similar problem last year.

i think what you are talking about is spraying carb cleaner or starting fluid around the vacuum lines and when the idle changes you found a hole.

Buy a vacuum test gauge and try it out. They're like $20 at Autozone.

A healthy 5.0 should make 17-22 lbs of vacuum, steadily, at idle...mine makes 16 at idle while cold and works up to 17 at idle hot.

Click to expand...

An exhaust leak would most likely sound like a metallic ping.

You can do that, too. But what's cheaper? Taking it to the shop .... or getting a vacuum tester? Even if you still can't find the problem after testing it, you may need the tester in the future. Be optomistic.
