I just changed the cabin filter of my ES300. I found the instructions on the manual, under airconditioning and audio. It's pretty easy to do. I bought the filter from Kragen's for $21.95.

SOURCE: hesistaton at idle speed. how many ignition coils are used in a 98 lexus es300?

I looked it up on and it looks like there is only one coil.  You can verify that by giving them a call.  However, to me it sounds like you might be having a problem with your idle air control valve.  Since you are only having problems when the vehicle is at idle I would take a look at your IAC.  It is located on the throttle body and is usually held on by two screws.  When the IAC starts to go bad you will have problems with the vehicle when idling.  Let me know if you have any other questions.  Thanks for rating my response and for using FixYa!

SOURCE: ES300 Lexus cylinder misfiring

well a compression test will tell you if the engines internal components are working properly and it is critical you start there when having a problem like this.

testing the injectors will let you know if they are giving fuel to the engine. there are two test for the injector and first one you do is an electrical test to see if they are getting turned on and off as they are supposed to and it they are internaly good electricaly with is done by listening to them with a stethoscope to see if you here the clicking sound the pintle valve makes inside of them. then there is the test to see if there spraying fuel or leaking fuel witch is called a leak down test and is done with a fuel pressure guage and a tester that will electrical turn the individual ijector on to see how much pressure it drops.

this is what i would do if i had it in my shop.

let me know if you have any more question and that you understood what i described.

99 Lexus ES300 - Car hesitates & sputters when starting off usually until 2nd gear kicks in & sometimes when going uphill. However, no CEL. Ideas?

The flexible accordion hose that connects the MAF to the throttle body might have a small crack in it. They are sometimes hard to see, especially if in the accordion folds or underneath. Starting off or going uphill will result in enough torque to lift one side of the engine enough to open the crack and cause hesitation.

Spitting and sputtering like not getting fuel

It may have fouled your plugs, but you can tke them out and clean them. Use a small blade and scrape the carbon off.
You could also take the egr valve off and try to clean it. Use a wire brush. also clean as best you can the passages under the valve, they can get plugged with carbon. Use a new gasket when you bolt the egr valve back down. Keep trying to get the fuel filter off, but the egr cleaning should help.

2004 GMC sierra 5.3 eng 1500 transmission shutter 40-55 mph

I too have that problem. I own a 2005 GMC Yukon. Shutters between 40 + 55 mph. I thought for sure the stumble I felt was a plug or coil pack because it only does it under a load. With A/C on the whole truck shakes! But it wasnt the plugs or coil packs. Answers anyone?
