Two days ago I replaced my last two injectors with low milage used units... smoking has reduced drastically, and my power has returned quite a bit. Having said that, and accepting that at least one of my remaining injectors was probably faulty...
Hijacking welcome!
I have since replaced my EGR with a known working unit, and replaced my last two injectors in the same condition. My car still smokes black under load, and I am convinced my MAF readings are too high.... no one can tell me...
