I am running out of ideas on this one. I've replaced the EGR valve, and
cleaned the ports with carberator cleaner...and I still get error DTC P0401.
I read on the net somewhere that there was a recall/service bulletin for
the '99 TL concerning EGR flow problems, but not for the year '00.
Has anyone had experience with this problem and can offer me some advice?
Thanks in advance.
