Keep getting a p0174 (lean right bank) code
#21
I can't remember ever getting a hard O2 sensor code w/o eventually needing the sensor ... if not an immediate need.
We actually had some difficultly testing the fuel pressure -- it was always OK (when we checked). And the symptoms directed elsewhere ... it's always difficult situation when an intermittent issue does not show itself.
I'm not one to throw parts at an unknown problem -- unfortunately, sometimes the alternative is an unreliable car .. and that's not acceptable.
The R will energize the second pump initially on startup of ignition -- then the primary pump runs until the second pump is needed at high fuel use. I must have had two partially working pumps.

I have and it didn't look too out of the ordinary to me. I just haven't been able to screen shot it and put it up here for someone with more knowledge on that to look at. Car has been running just fine sans light again for the past 100 miles.

Just understand, as I said above you may be having 2+ issues (like I had) .. I'm not sure why the trim level lean would give you the restricted performance engine management outcome ... you would get the CEL when it occurred (I think two hard cycles). I never got any CEL light .. I could only feel a slight power loss if at very steady speed and smooth road .. not enough to even give me a knock warning.
