Okay after replacing the egr and straight guttin' my cat converter it still was running really rough....The check engine light was still on and I didn't know what exactly to do. anyways a friend stopped by and said it was a coil pack or the plugs were lose. the last one was loose, he tightened it up and check engine light went off and it was running normal again.
