Have you tried: vacuum control solenoid (part #8-01997-201-0)?

"You can check to see if they are malfunctioning by simply spraying the outer edges of thesegaskets with carb cleaner to to see if the idle goes up while running. If the idle changes, the gasket is leaking and you will get CEL codes. (Typically, 171 and 172, if my memory serves me right.)"

couple of questions

We meet again, blue-faced question marky guy. Here, let me explain. See that dude chilling out, eating popcorn and sampling his preferred beverage as he settles in to watch and enjoy the playful ribbing between his two friends Tom4 and Dub? That's me.

In my opinion, I would pay particular attention to the four sentences that begin with, "The number of test samples required to..."

How many times have you driven (keyed/started the engine, keyed/stopped the engine) your VX since replacing the EGR? This is what I meant last time when I said that a vehicles' PCM requires a certain number of inputs before it can determine what normal operating conditions currently are, (aside from the hard-coded-parameters/factory-settings that are considered normal operating ranges for each particular sensor).

Have you actually had your PCM reset to clear all old codes since replacing the EGR?
