So for the last month and a half my SES light has been going on, and off.

When it turns on it stays on for about 1-2 days, and then turns of for about 4-5 days. Then Back on again. I got the codes pulled at Autozone, and it was P0171, and P0174, i know that these are for o2 sensors. The car is still under the factory warranty, but i cant get it to the dealership cus every time i make an appointment, the light is off by then. I beleive it usually turns on after Ive been on the highway for over 25-30 min. The car doesn't drive any different though

My only mods are Fujita Intake.

This started happening about a month after the intake was put in.

I'm not sure what to do, maybe put the stock one back on, and see what happens.

Any input would be appreciated, Thanks

 

there's a similar thread for this, with other unhappy fuji intake members https://g35driver.com/forums/g35-sed...-problems.html

 

Take it to the dealer anyways it stores the DTC in the ECM even if the light goes off.

 

really? The dealer told me that if the light is not on, then they would not be able to diagnose the problem. Ill try calling them again. I will have to take off the Fujita, so that they don't blame the intake for the problem, correct?

 

I recently bought and installed the fuji intake and shortly after (1-2 days ) SES light came on. Did the gas pedal reset method i found on here and light went off. About a month later light has came back and now can't get it to go out. Thinking about just selling the fuji intake and doing the JWT pop charger + Z tube or a K&N drop in. not sure yet...

 

Thats funny that you say that, thats exactly what i just did. I picked up a Z tube yesterday for $35, and i am ordering the popcharger next week. The best price i found for the pop charger is $107.00 shipped. Although i loved the way that my black fujita looked, and sounded, i hope to gain a little more low end w/ the Z yube

 

yes fujita's have problems with thier MAF housings, its more prevelent on vehicles that have a MAF straightener, but they are inproperly sized, they have always have problems. But like anything else some people have issues and some don't, depends on where you live and how you drive.
