Celica Forums General Discussion Exterior o2 sensors

my check engine light wont go off after i ran the straight pipe. everything was put back, sounds like trd again, cept my o2 sensors arent working. i took it to toyota and they said my o2 sensors are "out of loop." meaning, they arent detecting each other. i think i might need new o2 sensors. does anyone know where i can order new ones at? also my car seems to lag behind at 3000 rpms when i floor it. it started happening after i f'ed up my exhaust. my guess is becuase the o2 sensors arent telling my car the right ammount of gas to burn but thats only my guess. but again, anyone know where i can buy new o2 sensors? and how easy is it to replace?

if its still under warranty, i'd take it to the dealership and tell them to fix it

they wont fix it cause i modified it myself. well, the shop did but.. i told em too. as long as toyota didnt do it, and i have problems, they cant cover it under warrenty. when they explained it to me, they used intake as an example: "if you get an intake, and it doesnt give any check engine light errors, its fine. but if they do something wrong and you get an error, we cant cover it" does that make sense? ive already talked to the shop about it, they said i need new "o2 sensor seats" which is a piece in which the o2 sensors screw into. he said it should fix the check engine light problem but im not sure. they already ordered them and they should be in by monday. i have a feeling the o2 sensors are fried tho..
