99 running rough

[ben_fishn]

Check engine light came on , started spitting and popping on inclines. checked with friends computer. 2 different oxygen sensor codes. didnt think that would make it run that bad so i changed fuel filter. seemed much better for a day. now back to same problem. skipping bad. im sure it is a fuel problem. fuel pump is about a year old. any ideas? would O2 sensors make that much difference?

Well I see no one has responded and its been a few days anything change or are you still at square one. I know fords are very sensitive about their O2 sensors but chevy's i have never really had any problems with. I would say start with the easiest or cheapest to replace and go from there. Give me an update and I will try and help.
P.S. the O2 sensors are doing just what the name implies, if they are giving bad information to the computer then yes it may make it run like a pos.
