Did The EGR Cleaning Thing

[SkidPlate]

Yeah, I was a little nervous about doing that too. However, I cleaned the tube with the engine running, carb cleaner causes the idle to increase a little. No other issues though.

BTW, it's been seven months since I did this and it's still running great.

I've read several write-ups about this and several just say to plug the exhaust port (large hole) to avoid the possibility of getting flames shooting out of there. I just didn't want to try it so I just now finished doing this with the engine off and it seems to have worked fine. Plus I took off the intake and did the throttle body too. And checked the PCV while I was at it. I didn't use the whole can of carb cleaner, but I came close. That's A LOT of carb cleaner. The EGR valve wasn't too bad, but it wasn't too good either. I'm not sure if my VX has ever had this done before, but I'm at 69K miles so if it hasn't I guess it looked pretty good for the miles. Like you said, I noticed a difference right away- mine also was idling high and then settling as you described, and that is gone. As is apparently normal, it didn't really want to start after doing this, but pressing the gas pedal while turning the ignition made it start up. The exhaust sounded a bit odd for just a bit, but I slowly revved it up a little and then let off and normal tone resumed from there as I gave it a little pedal. Throttle response seems marginally crisper. Very happy I did this and a big thanks to everyone here whose posts helped on the subject!

I've got a P0401 Error "EGR Flow Insufficient"

What does EGR stand for?
EDIT: Found it! "Exhaust Gas Recirculation" Solenoid Valve

It sounds like a bottle of carb cleaner will fix it, right?

I've never heard of the Sea Foam before. Does anybody know of any potential problems with it?
