If the O2 sensor(s) go bad, or partially bad, would you expect to see extra fuel on rundown from 4-5k rpm to idle, like in coming to a stop? In other words, lots of smoke (unburnt fuel) coming out exhaust if the fuel press and injector pulse widths normal....

 

well, i bought a new set of two, and my idle oil press., smoking probs and all are fixed....yeahhh!!!!!!!!!!!!!!
