Ok I went to Checker..the code was p0304 The girl said 4th plug misfiring..So I have looked at where the plug is, is there a trick to getting at it? Looks like maybe from underneath is easier than from the top. I have to wait for the engine to cool off anyway so I may tackle this in the A.M. I am in AZ and it's 110 in the shade.
Thanks for all the other tips where are all those things (knock sensor, O2 sensor,cam and crank sensors,etc.) A picture would be worth a thousand words; I am new to Subaru's engines. I have have done plenty of tune-ups and brake jobs on Honda's.. Is there a place on line where I can download (for free)a shop manual or general schematic for the Outback.
