hmm no idea wher or what an 02 sensor is,but will see what i can find on that. To finetune my description of teh symptoms its having .....You have to manually work the gas pedal to keep it running ...and it sounds as if youve pulled a plug wire loose like its running on 5 cylenders or something. Anything under like 2000 rpm it will surely die. But by continually working the pedal or by hand, you can keep it running atleast. which sucks.
ty for the info. I bookmarked it!
