hello:
my name is timothy
i own a 1993 lexus es300.
when i had purchased the car it seemed to be working fine....
i had noticed when the gas tank reaches under a 1/4 tank and i would punch gas to pass someone it would cut out and not accelerate!!!

Now that the cold weather is starting to come around it seems that when i start my car in the morning it doesnt seem to be running that well and when i put my car in "drive" it bogs out....
I then will restart my car and it will start to run better until the car warms up and then runs fine....
it sounds like timing is what needs to be done.....
i have already done a tune up e.g. wires, plugs, cap, rotor, fuel pump, throttle, temp sensor and the car is is still not running right and the is NO check engine light on
