Appears to be a Lean condition and a intake cam position sensor or sensor circuit problem.

Vacuum leaks, fuel pump, cam position sensor unplugged or wiring problem, counterfeit MAF.

What OBDII tool or software are you currently using?

OBDFusion is a much better option for driveability issues. Less than $30 for the App and interface. Get the VeePeak interface from Amazon, Android requires Bluetooth, iProducts requires Wifi.

Smoke Test to find air leaks:

Cheap fluid transfer pump from your local auto parts store or Amazon.

A few rubber gloves, rubber bands and some cheap mini cigars from our local gas station or convenience store.

Also get a good, bright LED flashlight to locate the escaping smoke. Look deep in the engine compartment and under the engine if needed. Do not forget the dipstick guide tube and the lower CCV oil return line. These areas may be hard to see from above in the engine compartment.

After looking for intake air leaks, remove the oil fill cap and allow the crankcase to fully fill up with smoke, then replace the oil fill cap. Check for cracks in the valve covers and leaks around the grommets, half moons and around the perimeter of the valve cover.
