Spark Plug Questions

[bruceb58]

What is the spark plug torque specification?

Also, besides the top engine cover and the front timing belt cover, which items need to be removed to access the center spark plugs? Looks like a large portion of the fuel injection air intake needs tobe removed.

18 N-m, 13 lb-ft TQ

The air intake duct and throttle body must be removed. (good time to

clean the throttlebody while it's off)

I'll be doing this soon on a 2001 GS300, any gaskets involved to R&R the throttlebody? Is spraying throttlebody with Gumout good enough?

Gaskets are reusable if not damaged

Use throttlebody cleaner if possible, some regular carb-cleaners can

damage modern EFI sensors/plastics or leave residue that can corrupt

Oxygen sensors..
