Hi guys and gals. Having browsed this forum a few times and finding it very helpful, I decided to join. I am the owner of a 1993 GS300 in excellent condition with 65K miles. The spark plugs were last replaced by the dealer about 8 years ago. In looking at the very thin plug wires from the distributor cap, I notice that they disappear under a silver cover bearing the Lexus logo. My question is this: if I remove the cover will I be able to easily access all the plugs, or will the throttle body also have to be removed? Thanks for your help and advice.

The throttle body also has to be removed, or slid along the studs to access the spark plugs. There is a coolant line under neath that will need to be pinched off and unplugged from your TB, and make sure to have paper towels and such in your spark plug galley so you don't get coolant down there.

Thanks very much.
