ok for about a month now my car has been idling like crap. it pops and idles extreamly rough sometimes, especialy when it warms up. pulled codes (no check engine light on ever) always get 61-91, hego not switching, or o2s lean bank 1. I replaced both o2 sensors last week and im still having the same problem. checked fuel pressure today and its at 34 koeo (saposed to be 30-35 koeo) so thats ok, with it running its at 35 psi-so i know thats ok also. it wont stall or or turn off but it sure really uses a lot of gas, my fuel millage has gone down so bad and when i get on it somtimes it smells like gas bad. I also noticed my exhaust on the passenger side is a lot warmer then the one on the left (note-lean bank 1) im thinking thats why. I checked the o2 sensors wires/conectors today and they both seem to have voltage but im trying to figure out why they dont work. any suggestions?
