The sensor didn't look dirty. I cleaned it anyway, and the issue seems to have gone away. MAF sensors are pretty sensitive.
If you think the sensor is clean, it might be getting a coat of oil on it, if your filter is the type you clean and oil--maybe you should re-clean the filter and apply a much lighter coat of oil on it.Hoping for a little help as I am having this same issue. I had the Takeda intake on my car for about 2 months, but now have run into this reoccuring check emissions system warning. It's pulling up code P0171 fuel system too lean. I just took the MAF sensor out hosed it down and let it dry before reinstalling.
After I checked the code at Auto zone and disconnected the machine the code seemingly went away. But after about 20 miles it came back on.
I'm starting to go crazy with this issue and might just rip the whole thing off and go back to stock or switch to a different brand intake.
Should I try cleaning the sensor again? Everything seems tight and snug.
Did you ever fix the problem?Hey guys - spoke (above) too soon. Light came back on today, but was off for about 2 weeks after cleaning MAF sensor.
Going to try cleaning it again tonight, and then stop getting gas at the usual location. Will report back with any findings.
