For some reason, replacing the O2 sensor w/ a new one solved my problem. Disconnecting it did the same as yours, improved running but did not entirely solve problem. They're only a $35 +- item. so in this case replacing that to see if the problem was solved worked out inexpensively as we were looking at a new AFM or ECU as the next thing to try! Anyone speak up here who can explain this w/ some real understanding of the situation? Dennis, Mark, Jeff, Benny Boy??? YMMV, Tom B.-not a natural mechanic
