Engine misses, overheats, exhaust smells sweet. on 1993 Lexus SC400

I wouldn't think that a bad head gasket would cause all of these problems but you never know. Has anyone else had this problem? If so, any help is appreciated.

DO NOT DRIVE THIS CAR ANYMORE!!! Unless you are into putting another eng in it.
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!
If this is the case, can I still drive the car, or am I going to cause more damage to my engine.
