Hi all, quick question. I have a relatively clean 97 Ram 1500, that seems to lack power once it warms up. The CEL is on for O2 sensor, which I bought, just haven't swapped. In my past experiences, the O2 sensors don't cause power drain when warm. Someone suggested the coil was bad and they are notorious for that. Any thoughts?

 

Yes. O2 sensors cause drive ability issues when warm. That's when the truck goes into closed loop and looks at the sensors. Replace it.
