my o2 went bad and never threw a code, made one bank run extremely rich, fouled plugs and made it miss really bad

hook it up to a scanner and c what teh 02s are doing , switch the 02s and c if the problem fallows

sounds like a bad 02 to me

 

thanks for the replies, will post an update sunday if new o2 sensors fix it

 

if new 02s dont fix it , at least u got NEW ones lol

 

well i got new ones, and they helped a great deal. the car still has a slight stumble on bottom end and im still not sure it is makin all the power it should be. i only got to run it for about a 1/4 mile after getting the new o2s hooked up. at least i am making progress. thanks for the help

 

well if u were running rich u most likely fouled some plugs if the the02s help alot, then ur stumble may be plug related

did u go for a drive after teh 02s?

i decided not to clean my plugs off, i figured i can blow teh carbon off by driving the car a little

after the 02s i started it up and it idle somewhat rough with a stumble , i reved teh car a little but , i held it steady at liek 2 grand and the about 2500 , the car started idleing fine so i went for a long drive , about 30-45 minutes

car runs fine now , maybe thats all u need maybe not, then afterward u can do some "spirited" driving lol

have fun hope u figure it out

 

i only drove it for maybe 1/2 mile at the most, i didnt have time to do anything else because i had to get back to school which is in a different city than my car. that also means i can only work on it during the weekend. ill take it out and bust some gas this weekend hopefully and see if it gets better, maybe run some gtech numbers on it. thanks
