Hey guys I've had this problem for a couple months now and for a while it only seemed to happen when there was moisture in the air and after a while it would go away after giving it some WOT. Now its not going away and I brought it to advance and its throwing an o2 sensor code, catalytic pressure below threshold, p1416 and cylinder 7 misfire. I removed the AIR pump and plugged up the EGR to deal with the p1416 but anyone got ideas on the misfire? Seems to me to be electrical if moisture was causing it.
