Most of the time it is the EGR MODULATOR and/or the EGR VSV as described above. Make sure the vacuum lines are also CLEAN as are the throttle body ports.

Hi Everyone!
I'm also getting the gall'darn P0401 code. Additionally the car has started, several days ago, running rough under certain conditions, most notibly going uphill? Going to try to find fuel filter just in case and change that as well. Ideas, suggestions?
How do you clean the throttle body? And other parts as well... I sprayed and moved the (piston?) area of the erg, seems to be working OK, I can see it moving while working the throttle. Light suction stalls the engine.
Cleaned filter in the (modulator?), going to try blowing through the bottom today, other tests yesterday seemed OK.
Going to check and or replace the VSV today, hopefully. GREAT post about that by the way. Is this the only one everyone thinks needs changing? Is there only two, this one and one near the gas tank?
The rubber hoses on top to and from the egr and modulator are clear, haven't checked the ones going down yet. I'm going to look at those and the pipe feeding the bottom of the erg. Any info on cleaning those in case I can't see what to do with them? Other info appreciated.
Thanks much everyone!
