Default Barely starts/runs after deleting secondary air pump

Hey guys, just got my car back together after replacing the trans, replacing the turbo inlet, deleting the secondary air injection.

Car is a 2007 forester XT 5 speed

The car runs great once warmed up but when first started cold it takes 3 minutes of trying to start it before it'll stay alive and then it runs like it has a huge cam for 30 seconds or so.

I deleted the air pump, blocked off both ports on the heads (driverside and passenger side), removed the valve from the passenger side but left the driverside plugged in because someone said it reads atmospheric pressure with that valve.


I need to fix this today, any help guys

Sounds like a leak somewhere. Do you have access to a laptop with Learning View? Check the learned airflow values.

If you have an Accessport you can verify that the atmospheric pressure sensor is working properly. Should return a value around 15 PSI. If that is out of wack it will affect drivability.
