Truck has 192K owned since new. Just tuned up..new plugs...new COPs..new fuel Filter ...super chips custom programed since new..running just normal for 2 weeks. Then like a switch starts high idling then surging with it dying. Flashed program back to stock to get codes. Two show after day and says both banks lean. Any ideas? Changed out ICV before codes..didn't fix.

 

Major vacuum leak - most frequently the PCV elbow behind the intake.

 

Right you are brother...took another and it appears it did break but ran until foam around it got sucked in that it started missing...little duct tape and it's good till the stealer ship across town. Thanks again

 

Check both PCV hoses and elbows

 

So before I screw up something...I just need to reach back there with a razor knife and cut boot off the connector coming out of the plenum. It's gonna rain all week and I need the truck so I'm being careful not to **** **.
