Default sulfur smell? knocking sound?

anyone have problem when accelarating?
My car stinks like crazy!!

I already saw an advior and they said they couldn't do anything about it.

One more thing, any of you guys have engine knocking noise(during idle, AT set at P or D. car in stop motion)? they also said it's normal but i don't think its normal, because it's def. louder than es350(loaner car)

let me know if some of you guys have same problems.

thanx

what problems do you have on accel?! please describe. when you accel from stop? hesitation? then jerk a bit? that would be tranny software issue, there is a TSIB on it, you can request a software upgrade

don't know any of the engine knocking neither

The smell of sulfur and noisy idling could be a bad Catalytic Converter. I had those very same symptoms on a Lincoln several years ago. It was a rattling sound and it did affect acceleration and performance.

You might also try another brand of gas. Some have more sulphur than others and other additives.

Any check engine lights?

Sometimes, even if a CEL doesn't come on, within the computer itself are stored pending OBDII codes that could give a hint to what is wrong.

Perhaps the vehicle is running a bit rich or cat issue as discussed ealier.

I get the same sort of sulfur type of smell when accellerating vigorously at higher speeds. It dissapates as soon as you start cruising, but I know what you're experiencing. No, it's not normal, but, there are many unusual things that have occurred in my vehicle. Not impressed with this flagship, certainly.

There is a TSIB for engine knocking at idle. I don't have any sulfur smell. I would say neither one of your problems are normal...
