Guys--Seafoam works great if you do it the correct way. Some people have not performed the Seafoam technique correctly, hence creating problems. Seafoam does not clean the injectors unless you put the bottle in your gas tank. You can somewhat clean out your intake by pouring small amounts into an intake vacuum line... The best way to clean out your injectors is to take the injectors out and soak them in a warm cleaning solution (preferably fuel injector cleaner). Or you can have them sent off and have them cleaned. Either way, you should have the injectors taken out and thoroughly cleaned every 60K or so...
