Yeah. I have found one tidbit of info for anyone else entering P0401, and EGR replacement issues, etc. in their search queries. Advance AUto has the wrong aftermarket part listed in the computers (sold for about $140). THey have the Isuzu part that I don't believe any stores carry, but can order, for about $240.
OReilly, on the other hand, has the correct replacement part listed in the computers (about $180). Funny thing, it's the same brand as the one Avance offers, but it more correctly has the plug vertically on the top. The one Advance has, has it on the top, but horizontally, so as to make it impossible to install on the VX. LIkewise, the socket for the plug has the retaing notch on the opposite side, so even if you could get the plug in while the EGR valve is in place, the plug would be tenously held in place by friction alone.
Oh, and it seems almost all auto parts stores have a military discount. All these years, and I never knew that...I coulda been saving 10% on the probably thousands I've spent, cumulatively.
And the Autozone in north DOthan, AL has unscrupulous workers who try and lie to your face and disregard posted sale signs that re directly behind them. Other than that, southern Alabamans are supremely friendly people.![]()
