OBD code P0301 indicates a misfire in cylinder 1 of your Lexus RX300. To fix this issue, start by inspecting the spark plug and ignition coil for signs of wear or damage; replace them if necessary. Additionally, check for vacuum leaks, fuel injector problems, or compression issues in that cylinder. If these basic checks don’t resolve the issue, consider a more thorough diagnostic to identify underlying problems.

My Lexus dealer in Tucson AZ quoted me $712.00.
First find the source of the rattle then determine what steps to take to stop it.
You need to a new oxygen sensor if you are getting a p1155 code on a 1998 Lexus. This means that heater circuit is malfunctioning.
The P0300 is a multiple miss-fire code. The P1130 & P1135 are fuel air metering codes. Generally speaking you want to fix the first fault code in the list if you pull multiple codes at once. One code can cause other codes to appear. Fix the multiple miss-fire problem, clear the codes and see if the other two comeback.
Take it out and get a new one!!!!!
Check the relay, there are 3 drl relay siting rigth above the radiator.
The code is showing a mis fire at the no. 1 cylinder. first I would check the spark plug gap and if that is ok would do a compression check. Hope this helps.
To fix the side mirrors on a 2000 Lexus RX300, first, determine if the issue is a loose connection, electrical failure, or physical damage. If they are not adjusting properly, check the mirror control switch and wiring for any loose connections. For physical damage, you may need to replace the mirror assembly, which involves removing the interior door panel, disconnecting the electrical connectors, and securing the new mirror in place. Always ensure that any replacements are compatible with your vehicle's model.
p0300 is a general misfire code, and p0301 is a misfire on cylinder # 1. Most of the time a tune up will usually fix the issue. While you are checking things it wouldn't hurt to do a compression test while you have the spark plug out. If you have done a recent tune up recheck the plug, and possibly check the fuel injector.

The ODB code PO441 on a Lexus GS 400 indicates an issue with the evaporative emission control system (EVAP), specifically related to the purge control valve. To fix it, first inspect the vacuum lines and connections for leaks or damage. Next, check the purge valve for proper operation and replace it if faulty. Additionally, ensure the gas cap is secure and in good condition, as a loose or damaged cap can also trigger this code.
