Need help CEL P0401
My Car:
1999 Mitsubishi Eclipse Gs
(Aftermarket JDM t4 turbo)
Jdm bov and intercooler
Precision turbo wastegate
and aftermarket exhaust
My Problem:
Ever since I have owned my car the CEL has been on throwing a code for a p0401, which I cannot seem to figure out because the egr valve seemed fine when I took it out to clean it and look at it. I have also noticed a severe decrease in gas mileage, and it slanted from around 24-26 to 18 which is almost as bad as the awd models. My atf gauge reads rich now and it never used to be that way and I am wondering if the egr valve would be the only issue becuase I have limited funds and I can't go buying tons of parts that won't fix the issue. Any insight will be highly appreciated. Thanks

We can sit here all day and dick around with this, and never come near the problem. When people hack these cars up and slap cheap ****ty eBay 'JDM' parts on (there's no such thing as ANYTHING JDM for the Eclipse, since the car was made in the United States only) them, anything can happen.
Take the car to a shop.
EDIT: That narrowband gauge is garbage, it doesn't mean anything.
