Ok, so my 2002 4.6 Limited has a rough idle or "miss" when its @ 1000 rpm. I have changed the plugs, downstream O2 sensors, cleaned MAS, cleaned IAC, cleaned TB, cleaned injectors (done by mechanic), adjusted TPS, ran seafoam through TB, all with no change. Also sounds like it has a light nock especially when I let off the gas. Almost sounds like there might be a exhaust leak 2. So should I change the upstream o2 sensors? Could it be a bad coil or injector? If so how do I test the coils and the injectors? I really need to get this figured out, its driving me mad! Thanks in advance for your help guys!
