When I get past 4000 RPMs, I get a intermittant lag in power. Could this be the fuel pump?:shrug:

It could ....or it could be the IMRC, Intake Manifold Runner Control.
Get a fuel pressure test done to confirm. In the meantime, change the fuel filter and remove the plastic cover for the IMRC. The heat could be causing an intermittent failure for the IMRC.

Its under the black plastic. It opens up the butterflys at higher RPM in the lower intake manifold.

So the black plastic could be hindering the lower intake from opening correctly?
