the three lights have been coming on (check engine, VSC, trac) and has been giving me code P0300 cylinder 3 misfire. Changed plugs with NGK irridium, swapped coils and still cylinder three. The overheal light comes on time to time and is using anti-freeze up.

All signs point to head gasket or something. My car has 31k miles? Any other possibilities?

oh and compression test is on the way

 

sounds like a head gasket what year and model

 

do the comp. test. luckily headgaskets arent too hard to replace as long as you have a shop check to make sure you didnt warp the head and what-not.

 

did compression test and everything is normal. i have an 05 xb. I did find a leak at the oil control valve. I dont know why that would give cylinder 3 misfire code though.

 

well.... time to start chasing the gremlins through your engine bay!

 

P0300 is not #3 cyl misfire. That would be P0303

 

yeah your right; thats the code I am getting

 

compression test were all right around 180. Did a block leak test and everything was fine. It's burning up anti-freeze as well. Any other tests I should run?

I have read other places it might be a bad radiator cap? But again idk about the cylinder 3 misfire
