So my engine light came on a month ago and i used my scanner and it told me that my motor was running too lean. It gave me code p0174. I cleared it thinking it couldve been an error or fluke. A week ago it came on again an the scanner told me the same code. This time i didnt clear it. However a day later the engine light turned off by itself. Should i take it to ford? Should i be concerned? The powertrain warranty is still intact, but probably wont cover it because the issue isnt with lubricated parts... I think. My only mod is a cai by c&l.

 

CAI without a tune will be you problem man. Is you car tuned also? If not a tuner should take care of if.

 

If all you've done is put an intake on but not a tune, the intake shouldn't be making the engine run lean. I'd definitely go to the dealer, as a blown motor is going to cost far more than whatever problem you have now.

 

If you put the CAI on yourself make sure everything is tight with no leaks. Leaks will cause this code.
