ok back from the honda dealer ($40.00 later) got checked for codes, I got
12-egr valve lift
14-o2 sensor
the mechanic told me that my egr valve is probably clogged. Guess how much the part is? $189.13 from honda. Does anyone know where I can pick one of these up for alot cheaper? Part # is 18011-POB-A00. The reason why the o2 sensor kicked in the ecu code is because I don't have one in the header, my dc headers dont have a spot for one and I didnt want to drill a hole. So I think that everyone that is having the same problem needs to check for codes and will have to replace the egr valve as well? Nikon44 & RYounk007 I belive you have the same problem as I do. If, and when I find a good price on the egr valve I will let you guys know.
