From what i've read code 13 is the cam angle sensor and 22 is the knock sensor. Block is a 92 ej22 with a 91 harness in my ej swapped hatch back. It will start up and run with the high idle then drops down to about idle then just dies. A couple times it acted like it was searching for a rpm going up and down then dying. It will keep running if you put your foot on the peddle but it will miss and possible back fire. Ran great the past 2 days until tonight when i was done tightening up all the lift blocks to be safe... I'm guessing it's only one of the sensors but it might be both won't find out until tomorrow night or sunday. I have spares off 2 motors but would like to know what some of the more experienced ej guys think. Thanks in advance.

Turns out the code 13 is a 12. Which is the ignition starter switch. Any ideas.

Replaced to knock sensor with a new one from napa since all mine are cracked. Fill stupid since i didn't notice the IAC hose popped off and that's the only reason why it wouldn't stay running. Put on a longer hose and now i'm good to go to bnw subaru show once i get a few more things done.
