Hi All,
I have a MY07 liberty wagon with 34 000km on it, 100% stock.
Over the long weekend I threw a P0171. After resetting this it happened again after 20km, and then again after another 20km.
Thus far all I have done is cleaned the MAF, given all the vacum hoses a good looking over, put in a tank of 98 octane fuel and given it a good hard run.
What I am noticing it is struggling to maintain idle when cold and it some times hesitates when accellerating.
Subaru want to ultrasonically clean the injectors, a company who builds Subaru race engines are suggesting an additive.
Any ideas guys on what the issue could be. I was thinking of changing plugs incase of a weak spark.
