"I bypassed all the extra stuff on my 22RE and ran a vacuum line straight from the intake to the FPR."

Thanks 4crawler!
but.... what does the vacuum solenoid do that is upstream of the fuel pres reg? In my Haynes, it mentions that the system turns it up and down depending on speed. ?? you did not notice any difference when you removed it?

Anyhow, my TPS was always thinking the throttle was open, never closed, so I adjusted that, and tightend the clamps better on the MAF hose. We'll see next time I drive it.
