Well took some time but I changed the coils but it still have the same problem. If nobody has any ideas I going to take it to the dealer. I didn't want to do this since I had some bad experiences whit the dealer near me and the other are kind of far.

Thanks

Well I'm not a mechanic and I don't really have the time to be But I still have some knowledge. I talk to my mechanic and see what he think. He was on vacation when the light went on again so didn't have the occasion to talk to him. I just wanted to see what people would suggest. I read somewhere that the battery could be at cause for some code. I wanted to change mine before winter, it's 6 or 7 years old so might has well try it.

Hi I have a 2009 Legacy 3.0R with about 90 000 Mile and I have the errors core 302, 304 and 306 so some misfire on the same side. I changed the spark plug and it was good for about a week and then the check engine light got on again. What do you suggest ?
