Fuel Injector Cleaning

[lexuseng]

Does anyone have instructions on how to do a fuel injector cleaning, the type of service the dealer wants an hours worth of labor for?

I just changed the spark plugs and I cleaned the throttle body when I changed the timing belt but my 2001 GS300 (100K miles) seems sluggish. It did before I changed the timing belt too, I was hoping new plugs and throttle body cleaning might help but no difference. I'm reluctant to put in injector cleaning in my gas tank, I have had bad results on my older cars with additives. If you don't use them regularly, then I think it just breaks crud loose and makes things worse.
