I have a 2000 4 runner limited I bought in the fall . with a 3400 v6 with 125000 miles and I have a dead spot just off idle when try to drive it! so far I have replaced both 02 sensors /coolant temp. sensor /throttle pos. sensor/m.a.f sensor/fuel filter/plugs . cel comes back on after I clear codes and says bank 1 lean thought maybe I got a bad 02 sensor and replaced that one again. still have the same problem!!not sure where to go from here this thing runs great other then having this problem by the way I didn't have this dead spot till I changed the front 02 sensor and when I read the code it says bank1 lean
