Ok guys i fixed my plumenum leak last week and ever since then it wont idle well once it gets warmed up it will start to die. I just read that post and read how one guy just had a bad O2. Mine are bad but they been bad ahwile and havnt had any problems. Also you can hear a whisle nosie as it starts to die like its trying to save its self

 

Not real good at this, but I will throw out the idea of a vaccuum leak?

 

no cuz vaccuum leak would make it idle high

 

Sounds like the idle air control.

 

Why you think it would jsut mess up right after i fix the plumenum leak.

 

Hard to say. but you don't have to necessarily have to replace it. pull it off the throttle
body and clean it, then reinstall. when you have a plenum leak it will dirty up the sensor.

 

which one is it you have a pic

 

Its the sensor on the back of the throttle body, its the only one back there.

 

"Plumenum" Haha ... that's a new one.

Like it or not, the fact that it's a "warmed up" problem points to the upstream O2 sensor.

 

heres the idle air control and where it goes
