Custom Intake....

[Bluestrick]

Hey, so yesterday ive installed my own custom intake in my 09 mazda 6i touring. auto. 6.5k miles
well as i was driving to school i got a check engine light and so i looked it up by asking the auto's teacher
im running to lean... is that common for any of you guys?
what do i need to do? should i put back the factory box?

CEL will need to be cleared . . . autozone used to read/clear codes for free, not sure if they still do.

Did you change the diamater of the pipe where the MAF is mounted?

With some cars, the airflow sensor is sensitive to changes made. If you used larger piping, an open-element filter, etc...it could cause the mil code to appear. Reset the ecu and see if it is adaptive.

alright so i cleared the code, and i put this plastic piece around the filter to limit the air but while i was going to work, the light came up again about it being to lean.

so i dont know what to do.. and i dont feel any difference in the cars performace....

of anyone of you that have a custom intake... do you guys feel a difference and when you rev the car up do you hear the intake at all? cause i know in honda's you can hear the intake loud and clear.

Cause Vtak kicked in Yo

Might want to try the Aem airflow straightener to see if it help...

…wouldn’t restricting the airflow completely defeat the purpose of putting a different intake in…?

I assume this is the ghetto 3” exhaust pipe shoved into the stock tube with a K&N cone slapped on the end? Did you disconnect the car’s battery to let the airflow sensor reset? That’s all I had to do on my old car, not sure if the Mazda’s sensors are adaptive and can “re-learn” like the other guy stated already.

OMG free revving to redline FTL. Please don't do that anymore. Now that I've said my piece, the mufflers sound pretty good.

Dunno if this is whats going on, but you might be "pegging" out your MAF sensor. It doesnt seem like just adding a CAI would do this but if more than the maximum normal amount of air is going through the sensor then it wouldn't be able to adjust the fuel injector to compensate. This would cause you to run lean. Again i dunno if a CAI forces enough air to do this. I say put the stock intake back on and see if you still get a code....But I'm not a mechanic so take it with a grain of salt.
