Question about Lexus LS 400
First. Storing anything that is Gasoline powered for a long time ( typically over 6 months) should have a full tank of fule with Stabil or simmilar product in the tank and fog the engine. ( inducing a engine fog according to product lable)
As for your car I show that the Lexus LS400 has no external fuel filter. ( Poor Choice by Toyota in my opinion) the only filter that AllData shows for your car is in the fuel tank. If you have not *** of yet. I would find a place that sell Castle FireBall. It is the best injector and fuel system cleaner I have found. Try that first. If no luck you may have to try a professional injection cleaning. That would be my first try, if you have ruled out vacuume leaks. Letting a car sit can also cause dry rot of vacuume lines. Look it over good. Spray carb cleaner while engine is running on vacuume lines and see if you hit a spot where engine smooths out. if so that is a sure sign of a vacuume leak in that area.
