Toyota Camry: Cleaning EGR Valve

The "best" method? Ok, take the valve OFF the engine and with some
short semi-sharp tool (ie, pocket screwdriver) start poking and
scraping out all the hardened, baked-on carbon. Most of the worst
build up will be on the HOT (supply side) port. IF you find a lot
of carbon (to the point of occlusion), then you must give attention
to the matching supply pathway in the intake manifold (again, nearly
always the most carbon will be found in the pathway leading thru to
the exhaust manifold).

Thanks Philip, I did clean EGR valve pipes last week with Gumout Carb+Choke
Cleaner which states to be safe on oxygen sensors or Catalytic converters.
I've mounted a wire in a cordless drill motor to clean the EGR valve pipes
but I still could not clean valve tip.
I missed to clean the EGR pipe to the EGR valve and the exhaust system, I'll
take it off and clean it with a wire brush and gumout cleaner.

Thanks,
Iceman

Here's one other "inspection." Remove the EGR valve. There are two
pinky finger diameter passageways. One goes into the fresh air
intake stream while the other leads to the exhaust system. Plug the
one that leads into the intake air stream (vacuum). Now, start the
engine. There MUST be a strong blast of exhaust gasses exiting the
other port. If not.... then you know what you've got to do.
