replace your upstream O2 sensors

yep! but the only one thats throwing codes is bank 1.. HOS stands for Heated Oxygen Sensor btw.

bank one would be cyl 1-4 try replacing that one first but these are definitely O2 related issues. do you have the rear o2's installed as well or deleted?

yah i replaced the bank 1 downstream h02 sensors shortly afer these dumb codes started poppin up a while ago. ill def. look into the upstream sensors as well. i haven't deleted the downstreams yet cause i haven't decided on a chip. i noticed one of you is sniper tuned, thats what ive been lookin into here lately. me and my sis (02 GT) would go in halfs cause it says it can store files for two didfferent cars. is this true? is it really as customizable as it appears and would you recomommend it. don't be afraid to mention anything you don't like, thats the kinda stuff i need to know

my dad said something about maybe there a header leak on bank 1 cause the guy that i bought the car from had takin them off to put something on the car. he said he just tightened them up but didn't torque them. my dad said something about bank 1 may be "flashing" from false oxygen?

a bad header leak will throw a lean code. torque those down.
