Got any logs? Could be the primary oxygen sensor. Maf sensor is best oem, aftermarket is well known to suck
 
This is the only weird thing I can find this is with the car not running seems to not be bleeding off fuel pressure

Does it follow the commanded pressure when running? The high pressure side has no regulator to bleed the pressure off, either the PRV opens(around 2k psi) or the injectors use the fuel.
 
Do the KOEO test to determine if the relief valve is starting to go bad.
 
I had a very similar issue when one of my ground straps on one of my spark plugs broke off.

Check plugs.
 
Stulll fighting this fuel pressures are perfect across the board new plugs no help 1/8 throttle will rev all day any more and it spits supudders and stays at 1000rpm. Crank sensor has been replaced, checked cam timing and chain, no cel not sure where to turn other then an ecu issue

Have you checked the connector at your TB? Does it still have the red tab? Usually that red tab breaks off and the plug gets poor connection from not seating completely.

Are you sure you dont have a boost leak in your charge piping?
 
What are your mods? You should start with an introduction of what's done to the car. Maybe donate? Access metal side of the site that has much more to offer. Post your setup in the new member section?

This whole thread is useless without knowing what's done to the car or if it's even tuned.
 
Absolutely nothing completely stock

You gotta spill it all out man. At this point, it could be your tune.

More input!
