Sputtering at stop?
#31
Hi,
I have an 2004 LS430. The engine would shake and the idle speed would drop to 400 rpm. I live in Northern California so I don't believe it is weather related. It happens randomly with engine cold and warm. The car runs fine once the stop light turns green and I accelerate. I have not try to read any code yet. There are no service warning indicator from the car.

If this is the case, consider using an additive/cleaner like BG 9800 just before your oil change to help remove sludge and varnish deposits. Add to oil, run engine for 45 minutes, then drain and re-fill oil and change filter. Lexus dealers use BG products on high-mileage cars.
