By idling problem, you mean you feel engine misfires, CEL comes on intermittently and you can feel the whole car shake from the engine?

 

If so, could also be a failing battery/alternator. Low rpms = low voltage/current = no spark. Had the same problem, and would be at its worst when I restart the engine after a short trip, I could feel the whole car shaking from the engine/cylinders not firing.

Are you talking about a diagram on ALL the hose connections? There are a few resources floating around. Try putting your car number (found under the hood, in the format of BE5-XXXXXX) into partsouq.com and look around. Another is a full maintenance manual for same year Liberty's (Australian version of the Legacy), basically same as JDM spec but tuned down for Australia's lower octane gas.

There is no problem with the engine light... It doesn't turned ON while the engine runs....

 

 

 

I’m not sure if you really understand the question. Just to be sure what we are talking about is the CEL. Check for any diagnostic errors. You will need a specific tool for this.
