ok heres my problem i just got my megan headers installed and like all header owners the engine check light came on. so after talking to my mechanic i went to the scion dealership and they ran a complete check on my car and to my surprise the tech that helped me told me that i needed a new o2 sensor because of a current shortage. so i was just wondering if someone had a similar problem. any info can help. thanks

 

Take it to an Autozone and let them scan the car and see what code it is throwing... The dealership may just be trying to get money out of you...

 

i did that but the same code came up that their was a shortage

 

Well time to cough up some cash then.. that sucks.. Best of luck to you..

 

are you supposed to use an antifouler with a header?

 

is the code p0420 by any chance?

 

that was the next thing i was going try but i think it might not work, and for the code i would have to check again
