I HAVE A 2000 ES-300 LEXUS WITH 59K MILES. IT HAS BEEN A GREAT CAR! I AM THE FIRST OWNER. RECENTLY CHECK ENGINE LIGHT COMES AND GOES AND ALSO ENGINE KNOCKS WHEN ACCELERATING. I STOPPED BY AT AUTO ZONE THE OTHER DAY AND THEY TOLD ME THE CODE WAS RELATED TO FUEL BURNING RICH. COULD THIS BE BAD FUEL QUALITY (LOW OCTANE ETC...ETC...)

Hi there... this sounds like a possible O2 sensor. Did autozone give you the code number? that would help a great deal if you had the code number . we can look it up and find out what exactly it could be.

Hello fellow Texan!

AutoZone should have gotten more than 1 code for this problem. The problem could be any number of things from knock sensor to O2 sensors. More information is needed.

My 1999 Lexus ES 300 does not go into overdrive every so often.


If check engine light goes off then there is a trouble code stored. You'll need to retrieve the code w/ a scan tool and follow the proper diagnosis.

Check engine light on in 93 Lexus


The only way to check why the check engine light is on is to have autozone or a mechanic put a scanner on the car and read the engine codes. This will tell you exactly what is wrong. Many part stores will test it for free. Mechanics will charge about $40 But you will definately know exactly what the problem is.

If gauge is fine and car smells hot. It is probably due to plugged exhaust unless you have a wire laying on the exhaust manifold and it's melting.
