Failed emissions CO% Now what???
Still new to the world of BMW's- after going for my e-test, I passed all areas accept for the CO% AT IDLE. The limit is 0.7 to pass, but i paut out 0.91 . Mechanic suggested running diagnostics- but maybe there is an easier cheaper fix? I do have a OBD ll scanner, but again- I have no warning lights on. It passed at 2500 RPM. I guess it is running rich? I have no codes lighting up- so where should I start?? HELP!
