2001 camry 5s-fe stumbling code p0401
 

camry was throwing a code for o2 sensor. i changed it and it fixed the code. a couple days later throws p0401 for egr flow low. The car has been stumbling and misfiring.

when driving at 45mph and then braking the car will stumble and buck. nearly stall and then go back to normal. this has happened many times but is very inconsistent.

I was wondering what the problem could be. how can i test the egr system.
