Great video. One of the best I have seen for detail. I hope you make
others.
Had the same identical problem on my wife’s 2007 MDX. Spent 4 hours
yesterday (my birthday 12/14/13) performing the repair. Video was perfect
as well as the instructions, and pictures. A very useful and noteworthy
video. Thanks!
well i did the removal and cleaning of the intake and EGR valve yesterday,
and i did have the p0401 code popping up . i was getting enormous pieces
of carbon flying out hitting me in the face . Started her back up and no
code last night. But this morning the check engine light popped back on and
it gave me a P0404 code . WTF the general consensus on Acura forums seem
to be that their might be a piece of carbon that i couldnt reach let loose
and is now making the egr solenoid stick . So hooray tomorrow i get to pull
it apart again.
awesomely informative video. Egr valves are never in an easy to reach spot
and normally are attached to metal tubes that clog up . To alleviate this
problem from resurfacing you should use nothing but premium fuel in your X.
I have the same code and issues with my X, and will be doing this to it
shortly after i get it back from the recall of the trans fluid and flashing
the TCM. Really fast is there a way you know of to make the tire pressure
monitoring system reset or relearn mode?
