diagnostic code 43 1995 galant

anyone have any idea what this code means i cant find it any where. thanks

it means EGR system malfunction,good luck narrowing down the exact EGR problem cause the code is vauge at best,my 96 is throwing an EGR code and there is sooooo many components to the EGR system,if its the EGR valve itself it should be on the intake manifold,and its not the easiest to get too either
