Fighting a P0401 (1 Viewer)

[Simkins12]

I've been reading Flank's P0401 thread and have the parts but I am stuck on the upper intake plenum. I can't for the life of me see what I am missing.

Anyone in Round Rock area that could lend a hand? I've got to get this back on the road by Tuesday. Even just an eyeball to tell me what I am missing would be a huge help.

I've removed 6 bolts and 2 nuts and then tried to give the plenum a little force to pop up and still nothing, so I feel i am missing something.

I appreciate anyone's time and can compensate you.

Thanks,

Robert

Is this a 100 series?

Ugh, finally got it! All done and no more P0401

Clogged up EGR ports? I haven't wrenched on an 80 in quite some time.

Yes sir. I finally got the upper intake off and cleaned the plenum, TB, replaced old vacuum lines and related EGR system parts. P0401 defeated and gone. 1 week post-replacement and it sounds all good.
