Can anyone tell me why when I drive my car for a couple of day. While driving my car just suddenly shuts off. When I try to start it back up I smell gas and smoke comes off the tail pipes any ideas on wht it might be. Could it be the fuel pump?

What color is the smoke? Is is black soot-like? If so, your engine may be running "pig-rich" and receiving highly excessive amounts of fuel.

If the smoke color is white with a hint of bluish-grey, then it can be oil related(the smoke). In this case it still does not explain the gasoline smell you speak of.

the smoke is white. what could it be about the oil?

try to see if there any engine codes. Follow the instructions oneither of these links to find out where to place the paperclip/jumper wire (TE1 & E1) on the diagnostic plug in the engine bay.

Then count the number of flashes to find out which codes you have.
Post them here, and more people may chime in with possibilities. Make sure to put the paperclip on only E1 and TE1. Or you may blow a fuse somewhere.

Could be or you may need to change the fuel filter if it is the original one. I changed mine 3-4 years back and the fuel that leaked out was brownish in color. you can also use the search in the 2nd gen GS300 forums. There was a post a while back where a member cut his in half and took pictures. It was pretty darn bad on the inside.

I would still check to see if you have any underlying codes. some codes can exist without officially turning on the check engine light. It has happened to me before.

I have similar issues with my lexus rx330. The check engine light keeps blinking, the car shakes even when stationary with the engine on especially in traffic, and the car does not ride smoothly on the high way.

I took it to a mechanic workshop/servicing centre where it was suggested that it's engine spark plugs problem which I let them change all six. The air filter and adjacent parts were cleaned including the air flow meter. However, prior to the development of this "flashing check engine light" they have changed the passenger front shock absorberror, both shaft tubing protector, and the two steering locks (the thyroid, the previous day. The problem continues.

Today, I had the car scanned and got these codes:
C1223 (malfunctioning ABS)
C1246 (malfunctioning master cylinder pressure sensor)
P0304 (s1 and s2)

Please I need help for the interpretation of these results/code and how I will sort out these problems.

Thank you all in advance.

On a side note, are you in enugu? If so, how well is the rx doing? I personally know that is some tough terrain.
