hey guys, just yesterday my car threw a CEL. its a 2012 with about 50xx miles on it.

It was Code 45 Fuel system too rich or lean.

I did that DIY intake mod, the way FITDEEZ did it. Once the CEL came out I put the stock intake assembly back on and unhooked the battery for awhile.

CEL went away (of course) but came back on today coming home from work.

Anybody have this issue before and can shed some light on it for me??

Thanks in advance!

 

check for leaks around the sensor and clean the maf sensor.

 

will check that out thx!

 

And make sure all your sensors are plugged in.
