are yours acting up? how is your car acting if you suspect the O2 sensors are bad?

it runs great before the engine warms up. then pretty much as soon as it is warmed up, it hesitates and "stumbles" under part or whole throttle acceleration.

my car does that when its cold or warm, i'm changing my exhaust setup soon, and when i do i'm replacing the O2 sensors, so i'll see if that will help.

If it hesitates at WOT when the car is warm, then your O2 sensors are not the likely cause. The O2's are ignored at WOT.

But, if you feel like you want to replace/fix them, you can spray some CDC electrical cleaner on the O2 sensors. That should remove any buildup that is on them. Or maybe some carb cleaner if that doesn't remove the buildup.

Your Mass air meter could be dirty as well

so what do you suppose it is? distributor cap/rotor (not replaced since i got the car)? plugs (they were replaced about 6 mos ago too)? spark plug wires?
