I hear it all the time as it is a far stretch from the norm of my cars mpg. First i have a real time fuel meter giving me current stats. I can achieve that mpg at highway cruising not getting to highway speed or as a tank average mpg . Understanding that is the key that people fail to see. Unless you have a way to calculate your driving habits and usage you cannot determine how any modification works or if you are wasting gas by driving style. All mods have been done by me. Air temps and humidity play a major role but i also live in a city more dense than most . Unknown to most in the world is that we have 16 lane highways with grid lock stop and go traffic for rush hour daily. Only L.A. and another city come close to congestion. Also my 4 banger civic delivers the same mileage until it hits the highway which is where the LS sip gas and the civic does not. I am on air suspension so i can go lower with little change , although i can raise the front end slight to cause a lifting of the front end and it can produce better mileage. I get my best mileage at 40-50 km and 130 km

You probably have an lsd , depending on the package you have it will cause the lock up and setting off of the trac system.

Have a Lexus dealer start out by looking over the car. By the caliber of the questions this type of purchase is not your forte , have a pro look it over and they can give you answers.

Start by switching the sensors around to see if the problem moves. Have you cleaned it?

Like any dealer , i would look around and see if you have any Lexus specialists. Techs leave the dealers all the time and set up their own shop.

this months ?

I have a slightly different view of modifications. This largest factor is how hard you press the gas pedal. If you look far down the road and judge where and when to react with changes it saves a ton. Also most all power adding modifications are to free power from centrifugal or vacuum forces so it can be used to turn the wheels. So by reducing restrictions in the intake and exhaust , ensuring good combustion for a complete burn and having maximum air pressure in your tires to reduce rolling resistance. All of these things together will help you save tons of fuel. FYI i have a full cold air intake with a ram pipe forcing air so it runs slightly lean , a full exhaust with X pipe. Lowered more than most , new iridium spark plugs , motul oil ($100) not run of the mill mobil1 , removal of the viscous clutch to an electric fan , Leds for all non braking lighting for reduced voltage , almost perfect alignment and a good coat of wax. All of these things help bring my car above the standard for V8's never mind LS400's

So everything went well ? Keep us posted. 2 years later LMAO

A lock smith can get you in the car to retrieve the keys. You must have 1 working key to re flash the computer. No working key programmed and it needs to have a scanner hooked up to it. I am unsure of the possibility of using the tool to add a key but i think it can be done with out the computer being replaced unlike the older systems.

Fed ex to for ease of live tracking.

A good intake , sea foam and an exhaust . I get 39 mpg on highway cruising.

That is a very bad thing to do , the car needs atleast the same outer diameter , it will ride rough and the speedo is going to be off.

Toothpaste works great but you need to coat it after with wax or clear bra.

Simple and clean , now burn those mud flaps ! And too all you LOC brother in Canada.? Did you take the pics in Canada ?

no one with a 460 would have them as they are new and have warrenty if it failed.

It sounds fine , if it has ait their is a switch by the shifter for ride height and firmness.

Is it plastic or metal?

Their is one tsb for ucf20 's but the 1st gen cluster has issues of capacitors burning over time and gauges failing.

Agreed , run it under the console and carpet once the rear seat is out.

Depends on the year. If you have one in the center it is for the solar sensor which tells the HVAC to blow to the vents when the sun is blazing on you. The one right in front of the driver on the dash is the light sensor for turngin on the auto headlights. Why they need more than one i have no clue.

I don't see where it needs to be locked it is a matter of different opinions not any member insulting another. Kids want to have fun , it is their nature . It is the parents role to teach them the responsibility to know better.

egr

87 is fine as per manual as well as it being low compression

egr filter? their is no such thing that i have heard of ?
