is my 02 bad?
 

is there a way to tell if your 02 is bad?car runs like crap if i try to run my rpms high it makes a spuddering sound and it seems like my boost is gone the noise is kinda similar to like if you had a clogged cat...but my cats are shot and i just put on new mufflers a month ago,new plugs,and fuel filter. any ideas or suggestions?

well since you asked 20 TIMES! It's FUBAR.

honestly, pull the codes and see what's wrong.

probably not O2 sensor
checked your in-tank filter lately?

sorry about the extra posts...how do you check your intank filter? is it worth going through the trouble, or should i check other things first?

pull the codes??clueless

he asked if his o2 is bad. damn, where is this guy living? never heard of bad oxygen.

If you arent sure if your o2 sensor is bad just replace it. Go to kragen/pepboys or whatever and buy either a borgwarner or bosch replacement. They only cost $20-30.

About the intank filter it is pretty easy to get to if the screws arent rusted onto the lid.
