hi everyone, i have a 98 gs300 with 70k on it. My car seems to smoke for a really long time after warming it up. I understand if it were really cold but this goes on even after i had been driving it for awhile and the car is completely warmed up, and i know its not that its not cold because i live in the bay area. Also after a long drive it smells like if something is burning. Im starting to think that my cat is going bad. Can someone agree or disagree with this and is it worth changing? when i bought my car i was getting about 18-19 mpg and i did a full 60k tuneup and was getting 20-22mpg....now its back down to 18-19 again...not a world of difference but i guess everything matters with gas prices today. Thanks for any help you guys can give me.

White is moisture and it's more than likely a non-issue. I've seen cars running in warm temps (40+F) with lot's of moisture coming out of the exhaust, it's just part of the combustion process. Now if you car was running hot and the coolant level was falling you might have a blown head gasket or a cracked head. As the season warms up, I'm sure this will not be a problem anymore. Under load a bad catalitic converter will smell something like rotten eggs, pretty noticeable.

Everything is possible in this world, but it's highly unlikely for your cats to fail without a CEL and a corresponding code. Your car has O2 sensors in the exhaust system whose only job is to detect ailing cats.
Don't assume the worst. Take your car to a reputable repair shop and get it diagnosed. I'm sure you can tell the difference between vapor and smoke, and it's the burning smell that worries me a little. Good luck.

i drive the car everyday. If i just let it sit for 2-3 and drive it again, it will do the same thing and even though the temperature needle in where it should be the smoking wont go away for like 5-10 min
