i agree that unless you have a vac leak then its has nothing to do with the intake.

02'c could be bad...just replace them. and as far as "racing sensors"....just get stock replacement 02 sensors. i didnt know they make a "racing sensors"

i think i'm mistaking the MAF sensor for the O2 sensors then, is there a difference?

Boss_Hotrod

Yes. But you shouldn't fail a readiness code test for the maf since it's not checked.

A MAF in the sensor in the intake tube. the O2 sensors are the sensors in the exhaust. a Car can have 2-6 usually.

yea the o2 sensors made me fail, but im about to buy a brooksspeed tune and he said that bama probly turned the sensors off so i told him to leave them on and hopefully everything will work out, if not then oh well lol

It doesn't surprise me that some tuners turn off O2 sensors but it blows my mind that they don't tell the customer. I hear it time and time again, it's just crazy that they let people go for emissions testing knowing they'll fail..........

bigblue15

gah, ikr...if i had known that beforehand it would have saved me a whole heck of a lot of trouble, but oh well everything happens for a reason so there must be some significance behind this haha, im excited for my brooksspeed tune now tho especially since i've heard bama's in some trouble
