i just had the same problem. I replaced my egr valve back in july or so, but the check engine light came on a week ago, egr code.....all i did was sea foam into the intake vacume line(about half the can), drove around a while, popped it into neutral and red lined in like five times. the light went off, been a week, give it a try......how many miles on your motor?
well heres exactly what i did
