Hi everyone, I am experiencing a high idle issue with my Legacy. It is a 22T block with 25D heads and a 20g intake manifold. Ever since first startup its idled high (2100ish) until operating temp, where it will eventually drop down to around 1000 but trips a CEL and idles rough in doing so. It seems to drive ok other then the idle issue.

Here is what I find weird, I was moving stuff around while cleaning the IACV and noticed that if I pinch the hose going to the rear engine breather from the turbo inlet elbow, it chokes out the car. If I kink the hose, it will kill the engine. I am unfamiliar with these engines, but very familiar with the newer 2.0 and 2.5 engines, and I know they will run with that hose removed or plugged. Seems very odd that there is that much airflow going through that hose.

So far I have:
hosed out the IACV with MAF cleaner
Cleaned the MAF
Smoke checked for Vacuum leaks
checked throttle cable adjustment.

any advice on what to do next is appreciated

Hi,

What's the CEL when the idle falls to 1K?



What ECU? stock Ej22T
What injectors? 440's

I thought I deleted the other thread. My bad.

Are you still having a problem with this?

Just so I'm clear, if you pinch one of the PCV hoses it stalls the engine? If that is the case I think you may have some of the PCV hoses incorrectly hooked up.

this is how I have them. If I pinch off OR remove the hose to the inlet the car will not run at all.

This is how I recommend you hook up your PCV system. You need to have two separate connections going to the turbo inlet hose like I've shown in red.

I will give that a shot. Thank you!
