2001 Lexus ES300 Problems

Check Engine Light Due to Failed Oxygen Sensor

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

Low Engine RPM or Stalling on Cold Start

The 1993-2003 Lexus ES300 may start and stall, or start and run at very low engine speeds when the engine is cold. 

The issue is a failed or dirty idle air control valve. This valve is mounted under the throttle body, and modulates airflow to the engine under certain conditions. When the valve becomes dirty, or when the valve fails, proper airflow to the engine is not achieved. This results in start and stall, and low RPM.  

To correct the issues, the idle air control valve will need to be tested, and cleaned or replaced. 

To help decrease the frequency of this issue, change the air filter no less than once per year. 

Rough Idle and Backfiring Engine with Check Engine Light

The Lexus ES300 has a known issue with the valves that if left unchecked, will cause burned valves and engine performance issues. 

The engine ‘breathes’ through valves that are pushed open by the camshaft, and closed by springs. When valves are closed, they seal against a valve seat. In this vehicle, the valve seat is too soft, so after the valve contacts it thousands of times, it becomes crushed. Once it is crushed, the valve can no longer make a proper seal, and the valves erode due to extreme temperature (burnt valve).

Symptoms related to this issue:

To repair the burnt valves, the cylinder head must be removed and rebuilt, which is a costly internal engine repair, however, this issue can be prevented through inspection and adjustment of valve clearances every 40,000 miles.

The car is just so comfortable to drive, sharp body style, full of luxury features. I'm planning on keeping it for a long time.
Just bought a 2001 Lexus ES300. Beautiful car. Drove it for about a week then the check engine and trac off lights came on simultaneously, followed by a little stutter in the engine driving down the highway with the cruise control on. Followed some advice on the web by disconnecting and reconnecting the battery and then spraying the air intake port that's near the air horn with some electronic'...
