i have a 97 ram 15 w 5.2 now truck will start run excellent till operating temp then it hits . two thing one you can be driving and then seems to lose all power you either have to clutch it and rev up or down shift and mat it to get moving . and the other is when you stop idle will drop right off and you can hear iac motor opening to compinsate and try to keep it going but if you turn truck off and restart will be fine for a while ... there are two codes in truck one is battery disconnected with in last fifty starts and that is fine other is 21 o2 sensor but from all my experience and o2 will not cause this issue there for im sure the issue whatever it is will be causing the 02 not to read right and set a code.... this is driving me up the wall has new wires cap rotor tsb has been done coil has been moisture tested for cracks or anything cat is not plugged runs too good and too long to have this as an issue and i can not anywhere find the egr so im sure mine is one built without ....

re cat: flow is consistant never changes , so im sure its not plugged but yes if i keep going like this it will indeed plug . and plenum no i have not done this as i just bought the truck and saw no reason to do such what is the issue with plenum ?> may i ask. and i will try to unplug pre cat 02 and see what happens but if i unplug it should that not cause and issue on its own ?

Well shucks, you just got some new experience, didn'tcha? The oxygen sensor can and very frequently when failed does cause precisely the symptoms you describe. Change it out with either a Denso or NTK part and your truck will get happy. Don't try the other brands because they're widely known to be iffy at best.

With no converter you don't need to remove the sensor from the pipe -- just unplug the electrical connector.
