so i put a intake on my 2001 225hp tt, huge difference in response and acceleration, breathes very heavy now

BUT now diagnostic says my o2 sensor is bad.

does the o2 sensor have anything to do with intake ? i thought it was the mass sensor or whatever it was.

so anyway long question short, how do you keep your sensors good with a intake? tune it after intake? or is this just a coincidence and i have to replace my o2 sensor?

trying to get this stupid check engine light off for the 2107922 time

 

If the code keeps coming back, you have a bad o2. The 2 are not related in any way and the ecu will compensate for the minor changes in airflow.

 

okay so you mean by sensors arent related it could be either one right? and thanks all put that thing back on and enjoy

 

if you read the codes, it will tell you which one it is.

i thought intakes doesnt make any difference in our engines that's why i still have my stock airbox. placebo effect?

 

not a huge difference? but its alot more repsonsive, picks up speed alot quicker cause its brething in air comosed to sipping it through a tiny little straw. its not gonna make it a 10 second car but you will see a difference in acceleration thats for sure,

 

if the o2 sensor is good. you might want to look into a o2 anti fouler
