What mods can I make to my car so it can drive luxury smooth and sound luxury quiet?

Could be a bad CV joint on the axles.

I believe you are saying the car will not start up after you have driven it for a bit and then shut off the engine. It sounds like a bad solenoid in your starter. If this is the case a new starter motor should fix it. If this is not the case then provide a bit more detail.

sounds like sway bar bushings

It is normal, if you're using low profile tyres or having too high tyre pressure. Observe the manual.

I would have a close look at the fuel pump.These are one of the weaker links in the vehicle.Key On -Engine off will run this intank electric pump for 3 seconds.This gives you an opportunity to listen for the pump and how it sounds overall(in a quiet place ,like a closed garage)...Sometimes a failing pump sounds a bit squeelish and loud,somewhat labored.A good working ,fresh pump sounds very smooth and quiet.Fuel pressure diagnostics might be in order as these pumps seem to work about like they sound....good luck

Stopped up converter?

HAVE IT SCAN.BUT MOST OF THE TIME WHEN CHECK ENGINE LIGHT COMES ON WHILE DRIVING AND IT DONT EFFECT ENGINE.IT COULD BE GAS CAP NOT TIGHT.A CYLINDER MISFIRE OR EVAPORATIVE LEAK.TAKE IT TO AUTOZONE HAVE IT SCAN THEY WILL DO IT FREE.

Had the same problem and all went away when i got rid of the Kumho Tyres.

My new Yokohama Geolander G051 are perfect, smooth and quiet.

How does the ES 300 fit your driving style?
Conservative drivers your dream come true, Smooth, comfortable and quiet, easy to control and predictable. This car is the one to beat.

Sporty drivers Electronic throttle is very responsive, handles well for a car with such a cushy ride, Not as powerful as the other cars in this class.

Fast drivers Should opt for the Adaptive Variable Suspension. The firm setting provides this car with the character you are looking for as far as handling goes, but for all around performance, you may be happier with a Lexus IS300 or maybe an Acura TL Type S.

The answer to your question - the IS-250 is a luxury model, and the IS is sporty.

Both considered in the same CLASS of vehicle - near Luxury.

Who should buy this car? A person who is looking for a mid-sized sedan that is a cut above the average sedan in styling, comfort, luxury & performance.


Thank you for using FixYa - A FixYa rating is appreciated!!

Replace front drive belts. There comes a time when they get so worn and polished that they just don't grip anymore.
