I would recommend a new egr valve and also the thermactor pipe is the pipe that goes from one head to the other...Its probably clogged with carbon...LMK

for 33 you should clean the EGR and test again, 44 I wouldn't worry about.
I had a 33 on my `91 and replacing the EGR didn't fix it, the EVR was the problem, the EVR is the sensor on the passenger side strut tower, the top of the 2 mounted there, it controls the vacuum signal sent to the EGR telling it to open up.
44 means the tubes are probably clogged up, but again not really a worry as it doesn't effect the CEL and it won't really cause a failed sniffer test.

44 will not set a light only continus memory most foxs have that code due to the tube or heads being glogged with carbon most likely cause the egr aint opening u should test for vacum to it before you go buying new parts hook a vacum guage to the vacume line and run it out side of the hood near windsheild i normaly put it under the wiper.. shut hood and drive vacume should be present under load...if so then change vavle if not trace vacume line down to switch on strut tower and back up to intake if good replace vacume switch

I also checked it with scanner and ran a test that checks the balance in the cylinders and it told me to check cylinder 1 and 2
