Your Subaru may be running rough because of an engine misfire. Usually your check engine light will come on when a misfire occurs. A common issue that we see that is causing the misfre are burnt exhaust valves. What usually causes a valve to become burnt, worn, or cracked, is excessive heat due to either lack of lubrication or excessive combustion chamber temperature as a result of incorrect fuel mixture. This usually starts out as a bit of rough running when cold, and this will set a check engine light, wit a cylinder misfire code. If you are having any of these symptoms? If so give us a call!
