way to test if yours are bad? do they cause power loss if they are bad?

O2's are not used at WOT, so the only power loss you could sense is part throttle acceleration.

There are simple resistance tests but I am not sure how well they work.

Gas mileage and part throttle cruise/accel will be affected w/ bad O2's.

wow 180 is bad... i get 300 a tank highway and 250-275 normal driving (mods in my garage)


very bad.. i have no idea whats up... I did a tune up last summer, tire pressure is always right.... what else, i do not drive like an *******.. I shift at like 2000rpm while cruising.... I just bought a 255lph Walbo fuel pump.. so i guess it'll help.. if it's not that I have no idea whats going on.

you guy are lucky i get maybe 140 to a tank, with only moderate driving. Car is stock except cold air kit. I cleaned tps, iac, and maf. I think i might go to pep boys and by a scanner and get the codes. See whats up.
