I have a 02 ws6 and it recently started running real rich. I went to auto zone and checked the codes. One of them was both front o2 sensors, random missfire and coil circuit G malfuntion. It has new o2 sensors and i checked the wiring looked ok. Changed coils and it still does it. Changed plugs and wires also and nothing. When im driving it starts cutting out and bucking. It runs fine WOT. Also hooked it up to a obd 2 and it said cylinder 2 and 6 missfire. Any ideas

I have had this issue before, I got all new plugs, and make sure they were gapped perfect and fixed my issue. but Coil circuit G malfunction sounds like a back coil pack to me

I changed the plugs and gapped them correct. Just put the coils off my buddys car that i know is good and its still doing it

wireing to coils? intake air leak? what is the MAF signal doing when its bucking? does is still do it with the MAF unplugged?

Change your fuel filter lately?

Yeah fuel filter could be it. I also like the mag idea. I've seen dirty mafs cause all kinds of problems and the fix was just to clean it
