I am gettin my high flows installed tm. They are part number 94106. i am getting two at the shop and installed for 220 does that sound like a reasonable price. how can i avoid a CEL?

 

Are they re installing the O2 sensors before and after the cats, or do you have eliminators? I have LT headers and 94106s and have the front O2 mounted just before the cat and the rear O2 mounted just after the cat on each side, and i do not have any CEL issues.

 

if they saw the front cats off? thats not gonna mess with the first sensor is it? they are relocating the second o2 after the cat what should i tell them to do?

 

With my headers I'm only running one 94106 per side. If i understand it correctly the front O2s monitor air/fuel information, and the rear ones monitor emissions. Take a look at this thread too. https://www.f150online.com/forums/ex...-mod-pics.html

 

dont touch the front cats in between the pre cats and the headers. Air:fuel sensor. put the o2 sensors AFTER the new high flows. you might need an extension.

 

not cats, O2s!

So i'm not the only one who makes an error here & there.

 

HAHA. damn. i never make mistakes either
