Answerthe cylnoid or has a blown head gasket or maybe overheatsThere is no such thing as cylnoid to answer the question. Get diagnostics run and look for a pattern in the codes. Likely you have an intermittent sensor or a leak in vacuum pressure that needs to be addressed. More likely a fuel delivery problem, check your fuel pump.
