Need Help with Check Engine Light - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I need some help. I have a 2014 Camaro SS manual with 48k miles on it. Not sure if it’s a coincidence or not but the car had a CAI on it for years but after installing the phasetek scoop it shortly there after started throwing codes P015D and occasionally will throw P015B. Now I’ve replaced both of those O2 sensors twice with factory GM units. The car will throw these codes and sometimes clear the codes over hundreds of miles of driving. I’m at a loss as to what the issue is. Is the scoop causing too much air and now the car needs tuned? I took images off my scan tool and a video of it reving and you can see the fuel trims seem off but the O2 sensors appear to be changing like they are supposed to. As a side note the car will hesitate/ jerk around 1500 rpm when decelerating or very light throttle. If it’s at that rpm under throttle nothing happens. Is that bad for the engine? It runs perfectly other than that small issue. I noticed when it throws the check engine light the freeze frame data always show the vSS I assume the vehicle speed at 119 or 120 but in reality I was going nowhere that fast more like 50 or 65 mph is when it happens

Is it possible when installing the scoop you introduced some foreign matter that got on the MAF sensor? Cleaning the MAF may help.

I could for sure check that easily but I doubt it. Never touched anything at that top part all of the scoop install was below the CAI box. But it’s an easy check and clean regardless

How old is your battery? you seem to have several unrelated things showing problems at once. IAT=0, Baro at 689psi. That can sometimes be an indicator of a low voltage to the computer.

Battery is only a year old. Did switch it up and put in an AGM battery last year with higher cold cranking amps.

Smoke check it for a vacuum leak. 28% on the STFT's is telling you something is waaaaaay off.

Okay I’ll see if I can find someone to do that. I can change oil and brakes and such but all the other stuff is foreign to me
