So, my service engine soon light came on. Hooked my computer to it, and reads that it's running too lean. Also, rough idle occurs off and on, while in motion and while parked. My warranty has expired. I think maybe a vacuum leak or dirty MAF? Help would be appreciated! thanks!

A P0174 lean code for bank 2

I have recently powdercoated my plenum so it was removed and put back together but i double checked everything all the hoses are securly in place. I'm really lost.

Any help would be apritiated.

 

Search for my thread about pending code p1163 that ended up throwing a light for P0174. In my case, replacing bank 2 sensor 1 o2 sensor made the light go away.
