1993 Lexus SC400 Q&A
1993 Lexus SC400 Question: Engine misses, overheats, exhaust smells sweet.
If the exhaust smells kind of sickly sweet, that really sounds like burnt coolant coming out of the exhaust pipe. I would have your head gasket checked ASAP by a good shop. And, yes, a blown or leaking head gasket can cause all of these problems and more. Best of Luck! - dandd
