Running rich
So. Me e420 is running well finally. Cooling issues solved. Fuel leak and stalling issue solved. But she runs rich. Has new tps, new fuel filter, new harness, new plugs and wire set. Getting blink code 4 and 6. Currently gas is like a year old or more. I think a little more. I just got the car and got it running again. Amy ideas? I don’t think old gas would cause rich, or rich smelling exhaust?

On your 124.034 with a 119.975 a 4=faulty air mass sensor; 6=a fault in the LH control unit------to test the control unit you need 1000 ohms between pin76 and 5---what is it?

Will check when I get home. Do I just ohm test between those two pins? (Sorry for the dumb question. I just wanna be sure )

checked it. It was good. Had a friend come check it because my sense of smell is aweful any way, it’s oil. Pulled the crank case vent hose off and checked it, was aweful oily. Started with it blocked off at the intake and it didn’t smoke any more. Guess that problem is diagnosed. Thanks for your help!
