An update. I switched the plug wires 3 and 4 and went back to have the error code checked again.. NO change it still showed 4 misfiring but didn't add three?? so I had her erase the code. Started it up and no engine check light. I drove it home 3 miles, still no check engine light and will drive it around for a day or two with the wires switched if the light stays off, I will then switch the wires back and see what happens. Maybe it was only a loose wire/connection and moving them has fixed it??? Too much to hope for????

Can I get some help on the location of the other items mentioned in case I have to change those in the future. And any advise on getting the plug out would be helpful it looks like it's really hard to get at it. I will try and switch the plug wires first to see if the problem follows the wire. Again, anyone have a site for downloading a Subaru shop manual or schematics???

Ok I get it the wire maybe or ???. I just was going to start with the plug and then move on if need be...

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.

I have a 99 Outback limited with 50,000 miles. What should/can I do to get the light off. What has to be replaced, cleaned or ???? NO work has been done lately.
