I recently replaced my egr valve about 4 months ago. I believe it was Mastercraft (mastercrap). I'm already getting codes for egr malfunction! I can't remember where I picked it up and O'Reillys tells me it wasn't through them. I've tried all the other auto parts places and can't find my purchase. I remember paying about $75 for it. Can anyone recommend a better brand or a way to fix my issue and get my check engine light off? I have to do emissions testing where I live. Thanks!
