The car is running as crappy as it ever has
It is a 98 neon r/t
I checked the codes and they read 12, 43, 32
12 is not a big deal but 43 is a misfiring cylinder(s), and 32 is a egr system failure
Has anyone ever ran into this problem, and if so how did you fix this?

 

Do you have an egr block off plate? Have you tried just resetting the ecu?
