& allso changed it from 4 2 8cylenders
so thats my lil bit of help

Did your 4-year old brother write that post?

As in switch it to a new computer?

He might be referring to people running a separate engine management system such as megasquirt. The part about the ecu erasing maps and switching from 4 to eight cylinders makes me think he's talking about MS.
You know an O2 sensor is bad because you will have a CEL. Do you have any? If so get them checked for free at an autoparts store and replace the supposed bad part. Then get back to us and answer Olderguys post.

you're honestly going to listen to that post?

do you have digital multimeter? can you respond to olderguy's questions?

HELL no that was more like a wtf post? i dont have the money to just swap out computers.. And i didnt really take nething else off.. Im not throwing codes at the moment... the car will start when its cold but when it warms up it stutters and s*%# at 4.5 ish so im going to change the o2 sensor in like 10 mins
