P0300 and others

[relentless044]

My 02 xterra has a p0300 (random misfire)p0328 (knock sensor circuit b1) and p0174 fuel system lean b2, it has a noticeable miss at idle and falls flat on itself at around 2k, under full throttle or heavy throttle it clears up, I got no smell like cats, no red dust under the distributor cap, and just sprayed all intake and vac lines with starting fluid and idle pick up, o2 sensors are brand new bosch

I would suspect the distributor too in that scenario.

the Butterfly was doing that and had a bad distributor AND rat chewed wires that took me a long time to find.

This is true. I bought two of those, and one (cheap) was bad right out of the box.
