Check the spark plug leads and spark plug, it may be putting too much fuel in the engine and not enough spark or power to ignite it leading to lower economic driving, also make sure you get the timing checked as this can set it off.

Make sure there is no black smoke coming out of the engine. It will be losing a slight amount of power from somewhere where it is either combustion related or even something simple like the aircon unit.

Your not running with A/C on? this saps enough power from the car

SOURCE: 92 lexus es300 knock sensor

Need to remove the upper and lower air intake manifold.  There are two knock sensors for the front and rear pistons banks.  If you plan to do this yourself it is about 1 to 2 hours.  While you are at it, there is a short coolant bypass hose sitting in the same spot, replace it.  Another problem with the knock sensor is the wire harness used to connect the two knock sensors into one connection sometimes wears out and contacts the metal on the engine causing false signals to the ECM, so replace this cable also.
Just did this last summer on my 99 ES300.  Pretty easy.

Are you sure this is a rattle or is it more of a creaking noise? I have a 2000 ES300 and had an issue when I would go over speed bumps and the noise would drive me nuts! However replacing the bushing in the top of the strut mount is expensive due to the labor involved.. Replacement of the strut or the bushing isn't necessary. Just open the hood, locate the strut housing and you ll be able to see the black rubber bushing in the middle. Obtain a can of Heavy Duty silicone aerosol spray and attach a straw to the spray tip. Using a flathead screwdriver wedge the screwdriver between the top of the bushing and the metal pushing the screwdriver all the way to the edge of the metal underneath the roof of the metal housing. Then pry the edge of the bushing away from the metal housing so that the top of the edge of the bushing exposed and stick the straw end of the silicone into the spot and spray generously. Only slight bushing movement will be obtained as the bushing is pretty stiff but it will be enough. Work your way around using this technique until you get the spray fully around the bushing 360 degrees getting it into the area between the edge of the bushing and the metal. Then spray the silicone onto the top of the bushing filling it all the way up until it spills over the metal. After it drains down, repeat again making sure you fill it above the rim of the bushing so it seeps into the area between the bushing and he metal housing (or frame) because this is where the rubbing is taking place that is creating that awful noise. Repeat on the other side and your done. The main goal is to get the silicone into the area between the metal and the bushing along the edge. This happens to be the way I was able to do it. This totally solved my problem and now the car is so quiet there aren't any knocking, creaking or rattling noises. This was a hard solution to explain without visuals, hope you can follow. This will work for sure. The Heavy Duty Silicone spray I used was manufactured by CRC and I bought it from Walmart.

SOURCE: how to replace third brake light on 1997 lexus es 300

"To get access to the 3rd brake light:

- Place each hand against both sides of the plastic housing, and firmly grasp and pull the housing towards you. It might not budge at first, but it should move once you get a good grip on it.

- Pull the housing out just enough so that you can see the brake light bulb and stick your hand underneath. Ignore the speaker wires.

- Pull out the old bulb from the socket (it plugs in/out). Wear rubber gloves when handling the new bulb, and put the new one into the socket.

- Reverse the steps here to put the 3rd brake light back into place. Test out your brake light, and you're done" quoted from lexusk8 @ clublexus.com (great forum)

40 psi sounds high. For actual recs check sticker on drivers door. These factory recs are a compromise between comfort and safe handling. For winter driving some people "up" the inflation for better traction in snow, etc.. Check the side of the tire for MAX psi (it's stamped from Tire mfg) You can use the tire mfg.'s 'max" rating safely. Over inflation will cause tires to run on just center treads.

What is the correct tire pressure? Is it less for the front tires than the back tires? There are no labels on any of the door jambs or under the fuel filler cap door.


LOOK IN THE OWNERS MANUAL IF YOU HAVE ONE!
I run 35 psi on all 4 tires the tires will have a maximum pressure rating on them.Which is high,example 40 psi and will give a rougher ride,and the tires may wear in the center or crown.over inflation is as bad as under!

2006 lexus gs300 tire pressure reset button where is it located?


there is not a reset for the tire pressure monitor system, the system resets its self when all tires are inflated to the proper psi. 35 psi . dont forget about the spare. if all tires are properly inflated check the "2nd set" switch. it is located under the dash on the passenger side. sometimes they get bumped accidently. unless you have a 2nd set of wheels with sensors the switch should be set to "main"
