Look for vac leaks, check EVERY hose, you unplugged one somewhere.

The main culprit is usually the one vac fitting that tee's at the top of the firewall directly behind the intake horn.

the line under the VP pump where does that go,[back to the firewall were those to nipples stick out]

oh yeah the t was also apart but that did not fix it

 

[steveo24]

it's gotta be a line somewhere that you broke or unplugged. Follow that T and see where else it goes, bet you'll find your problem then

I did the same thing when I yanked the head on my truck, I know this is the culprit, been there, done it several times. Start at the vac pump and trace ALL the lines out.

Had the same problem last weekend had the whole dash tore apart and here to find out it was just a vac line pulled loose in the engine compartment.
