VSC light and Check Engine Light On at same time 2003 RX300

I just traveled 180 miles to the beach and upon arrival, both lights came on. I looked in the manual and checked the suggested items such as the gas cap and then took to Jiffy Lube for a quick diagnostic. Nothing else was open to perform the check. Was told the O2 filter was bad but that it could just be cleaned and didn't need replacing. As for the VSC light, the manual said not to worry. Now that I have returned and both lights are still on I'm wondering the proper route to take for repairs or just resetting the lights.

    Yes I do mean o2. Upon researching on the 'net I found several people with the same issues. apparently the VSC is somehow related to the check engine light from what I gathered. However, they also suggested checking the hose behind the air filter if that had recently been changed... which it has when the oil was changed. Can an o2 just be cleaned or reseated and why would Toyota/Lexus have those 2 lights illuminate at the same time??

Need to take to a toyota or lexus dealer to find out what the code really is. the vsc light comes on every time the check engine light comes on. aftermarket scantools sometime will not give the proper description of the code that is present.vsc light is a vehicle skid control light. and do u mean o2 sensor.

Light says 367 miles to empty on dash

This is a readout of the estimated miles remaining in the current tank of gas. It is based on miles traveled since last fill-up versus fuel remaining in tank. Don't trust it, but is can give you indication of your approimate fuel economy.

Car shuts of suddenly while driving. Starts back up after 20 minutes.

When the gas-cap is plugged, you build up vacuum in the gas- tank and cause the gas flow to stop.
Use premium gas only, ETHANOL in the mix is attracting moisture/water which is part of the problems.

Thanks for choosing FixYa and welcome. Check your fluid levels on the car. One may be low and causing that sound you hear. More then likely, it needs a tune up. Change the spark plugs, wires, coils, coil pack, and distributor cap. Change the air filter and the fuel filter. Check for vacuum leaks on the engine. Change all your fluids. This will help your car a lot. Spark plugs will help your gas mileage a little, as well as the lack of power. This will help your car greatly.

I have a 2004 Lincoln avaitor and this week i noticed after sunday filling up with gas it started missing on my way to work monday am. when i got to about 40 to 60 mph the truck starts missing. It has 75k...

Once scanned and the codes suggest missfiring, Check your ignition coils. There are one unit atop the each sparkplug, and it is recommended to replace all upon performing a tune-up (costly). Purchase them on ebay and save $$!!Ford/Lincoln/Murcury vehicles with DIS and COPs (coil over plugs) systems are known for these coils to fail around 70-100k miles, typical early symtoms are random sputtering/missfire around 40-60mph with foot slightly on accellerator. If this is the problem, it will progress to stalling, severe missfire, very poor MPGs, rough idle!!Hopefully this helps

Nissan Sentra 2001 gxe with code p0420

You will need a new catalytic convertor assembly. Yours is below treshold efficiency in other words its "no good".If you have it replaced, ask the garage/dealer to give you the old one back. Its worth some cash if its full. It doesn't matter thet it failed. They are going after the mesh inside of it and that is worth some $$$$. May not be much , but better than nothing.
