my 93 22re 4runner(auto) starts up fine, runs/drives fine when cold, but it seems as though once its warmed up its very sluggish to the point that it will barley make it up hills. it also has a very rough idle. i know for sure that the front o2 sensor is broken but i was told that it wouldn't make a difference. any ideas as to whats wrong? ive researched this problem and it seems like alot of people have it but i havent found a definite answer. any help would be greatly appreciated
