Just installed an MST Inlet + MST Intake today, however after starting the car I got a CEL, I checked my lines for proper tightness, and made sure the crankcase was properly seated. I'm not sure if this error is because of the increased air intake into the vehicle but these are the codes I got :

118001 - Mixture control: Fuel-air mixture too lean

118401 - Mixture Control: Mixture too lean, large deviation.

Also to mention the cold starts are a bit rougher with a higher RPM on start and then it settles down. I've also cleaned the MAF sensor, research on this problem I see others suggesting to just unplug it , but I'd like input just incase.

Any help is appreciated.
