EGR valve question

[x_monster]

Hello, I'm new and and hoping someone can help me out. My 96 2.2
has been sputtering, mainly at lower rpm, and my mechanic said the
diagnostic gave him back a code indicating the EGR valve. My questions
are, does that seem to be a common problem, and if so, has anyone
replaced it themselves. If so, a description of location and what it looks
like would be really helpful.

Thanks in advance for any help.
