I did a search, but none of them really described my problem. If I am sitting at an idle it jumps up and down alot. If you ever heard a mustang with a big cam in it, that is what my car sounds like. It just started this today. If I tap the gas to bring it up a little bit I can hear a big sucking sound that goes away real quick. Any help would be appreciated.

Yup what they said. Check all your vac lines and I'll bet you find leak somewhere.



Oh, you don't like altezza's? Too bad, your gonna get a good look at mine.

I thought that too. Then within 30 mins after posting this it completely went away. I dunno?

It may be a vac line, but it could also very likelly be the PCV valve...
The PCV valves on our cars suck, and can cause lots of weird idle problems
