Hi I am new. Just purchased a 2002 ES300. Love the car. It has 55000 miles mark levinson, navigation. Yesterday the check engine light came on. I checked the gas cap and it was tight. I am going to take it to my mechanic in a few days. I was wondering if there is a way to check the error code in the car.
I know that in Grand Cherokees there is a way to check the error code, it reads out on the odometer. Probably a way for the dealer to save money! I always did it on mine and saved time at the dealer.
I have a feeling it is the 02 sensor.
I put 93 octaine in it.
Any help would be appreciated.
Also are there any performance enhancments for this car, I am having trouble finding anything nice online.
Thank You
