Good day all. I'm new to this mini repair and this is kicking my hip. the car had three initial problems. Rear oil leak, Valve seals, steering rack. after getting in we realized the rear leak was actually coming from that screw and not the rear seal. However we still replaced the rear seal. I also went back in the valve cover and rechecked the timing. but ever since putting the car back together it now has an off and on idle.. periodically the car even shuts off while driving. I have replaced the vvt (located at the rear of the valve cover) I have replaced the pcv valve. I have also replaced the air mas flow sensor.. But I still continue to have
CODE 2EF2 INTAKE AIR TEMP SENSOR SIGNAL.
2AFC DIFFERENTIAL PRESSURE SENSOR SENSOR INTAKE MANIFOLD SIGNAL
2B68 MASS AIR FLOW PLAUSIBILTY
Does anyone have any idea what is goin on with my car.
Any help would be appreciated

 

maybe your crankshaft trigger wheel is damaged ?

 

Remind us if you did a visual and tactile inspection of each hose and clamp along the intake tract to ensure everything is secure. A hose may "look" attached, but in reality, be loose -- pull on each connection, particularly those underneath the car if you have a turbo.
