2bea mixture control. Fuel air mixture too lean
Hey guys getting codes 2bea and 24c2. After replacing my spark plugs, coils , valve cover and ,gasket, belts pulleys, even the maf sensor. I am experiencing a rough idle and when coming to a stop and hitting the gas again slight hesitation. Hpfp has been replaced about 10k ago as well. Im getting irritated because i don't know where to look next? possible air leak somewhere? Oh yeah and hpfp rail pressure sits at 700 at idle and does not dip. I will try to smoke test this weekend. Afrs sit at 17 . When i unplug the maf they will go to 14.7, but the car drives like shit, will only help it idle better.

Sounds like it could be a bad MAF. Do you have a K&N air filter?
It could also be a blown charge pipe, or a leaking Crankcase Vent Valve...
