Hi all im new to the lexus world i have recently bought a lexus is200 navigator it has 85k on the clock and is a automatic, well for the advice i need: the car cut out today for no reason and it is idling quite low when stopped and parked up but this is what i need to no when i reved it quite hard a puff of smoke came out the exhaust and that was it. The car has been stood for a little while am i being paranoid over nothing or is this a sign of my head gasket going.
PLEASE PUT MY MIND REST. Thanks
Stu
