Default 2001 Camry - EGR system issues

Got a CEL (believe it was 401 - EGR Insufficient Flow) about 3 weeks
ago. Spent last weekend wrangling with the valve, try to get it off and
switch it out. Well, I got the 2 rear facing bolts off, and one of the
bottom bolts out, but was unable to get the last bolt to move at all.
In the process, I snapped the tube that comes out of the bottom. After
spending 3-4 hours trying to get the right parts, the bolts off, etc, I
gave up.

Anyway, I took it to a shop nearby, and they swapped out the EGR valve
and VSV and cleared the code... The CE light came back on about 2 hours
later. Did they not clean it out properly? I called another shop to ask
about what it would cost to throughly clean the EGR ports, and they
said the labor would run about $190.

AGH! What to do now? Pay the shop to clean it out? Get the guys that
swapped the part to go back and clean it more throughly? ANY
help/advice would be greatly appreciated.

The mechanic who performed the work has an onus to fix the problem. Now in
times past in such a situation as this, the shop involved would take the car
back and fix it properly for free as they failed to do the job properly the
first time. But in these times, they may just have another go and charge you
for the extra work. I'd check your consumer laws for any information on
this. If they want to have another go at your expense, I would go to another
shop and put in a complaint to the industry regulator on the first place.

Not necessarily, Jason. If a guy goes to a shop asking to put a part in
that he was unable to, the shop is hardly responsible for the original
diagnosis.

Well, assuming the VSV you replaced is functioning properly and the EGR
valve is installed, hooked up, and has a clean path into the intake
manifold, the only other component left is the vacuum modulator. But it
sounds like some diagnosis is in order before more parts are tossed at
this thing.
Here is one thing that you can do to verify if the lack of EGR flow is
mechanically inhibited by a blockage of some sort or if it is a control
issue (like the valve not being opened for some reason).
On top of the valve there is a small vacuum port with a hose connected to
it. This is the vacuum line that physically opens the valve and allows
exhaust gasses to flow to the intake. Apply vacuum at this port while the
car is idling. By opening the EGR valve at idle, the car should stumble
and stall out. If this doesn't happen, then you know that the exhaust gas
is not making it into the intake manifold. I the car DOES stall, then you
know you have a control problem like a bad valve, dirty modulator, or
mis-routed vacuum lines.
Oh, and have you verified the MIL is indeed the same code as before?
I've seen stranger things happen.

You have to go through the proper diagnostics procedure. The valve
itself is usually very solid and does not go bad unless the silicone
diaphragm deteriorates (not likely in a 2001). And with the valve and
tube replaced the problem hasn't gone away then you know those were not
the cause.

You still need to check the control circuitry (that operates the VSV),
the EGR VSV valve behind the intake manifold, all EGR vacuum hoses,
vacuum modulator (again, not likely in a 2001). The problem can simply
be a plugged vacuum port in the throttle body that sends vacuum signals
to the modulator.

Do a search on how to check Camry's EGR system.
