Did you check all of the vacuum lines carefully? Especially the big intake hose by the throttle body?

1) Language please. And please use grammar that doesn't sound like we're texting a friend. You're not.
2) Sounds like your front o2 sensor has gone bad. Check the computer for any stored codes. Even if the check engine light is not on, codes can still be stored. I never had codes when mine did, so by process of elimination (checking for all air leaks, etc) I replaced it.

Have you replaced the MAF yet?
