I own a 2000 es 300, recently my car has been shaking rapidly whenever i am idling or come to a complete stop, also it make a puttering noise when i accelerate. I took my car to the local Lexus Dealership and they did a diagnostic test on it, and said that my 5th spark plug is bad and the ignition coil is too. They wanted to charge me $600!! to fix it. I figured I would do it myself, i found the front three spark plugs, but i cant find the back three. Also, im not 100% sure how to change the ignition coil. If anyone has unfortunately ran into this problem and knows how to fix it, please help me.
Thanks a lot!,
