Subject: Re: Running rich and hunting for idle by lunytnz on 2014/10/9 6:07:09 I disconnected both of the solenoids (for diverter and switching valves, I think; hoping they would close, by default, when disconnected), but it made no difference in the high O2 readings and it running rich all the time. I tried disconnecting the MAF, too. But, it also didn't seem to make a difference in O2 readings. It *could* be a rich, or leaking injector, but since 2 spark plugs looked the same, I suspect more a whole system problem. From looking, again, at the list of possible causes in the FSM, it could also be the ECM. I wonder about the EGR valve... could THAT be the cause? |
