Alright so a few weeks ago I installed a 57 series K&N CAI and after the install my check engine light came on. I got the codes p0171 and p0174. I had my manifold gasket and my o2 sensors replaced recently. I also double checked everything for any leaks, replaced some of the worn out rubber pieces to ensure no air leaks, and i even cleaned my throttle, but still the CEL continues to stay on. I'm just looking for any help to fix this, i emailed K&N about a week ago and they yet to get back to me so im looking for some help please!
Oh and there was no CEL on before the CAI install. Could the CAI possibly be too much for my truck?
