So you simply pour it right in the intake ?? Sounds like it'd help out some. Could you notice a difference? I found that it also comes in a spray......that might be more benificial for me, I could spray it directly into the throttle body, thats what others seem to have done. My truck has the throttle by wire also....

I like to use the vacuum hose to the brake booster and and let it suck in a little bit at a time. Most recently I used about 3/4 can of Seafoam, basically the same type of stuff as GM Top End cleaner. I've used the GM stuff in the past with great results, it really works and helps to remove carbon. If your engine is like mine, don't expect your noises to go away though, it probably won't remedy that. It's definitely a good preventive maintenance...I do mine about once a year. And yea, it's definitely fun when you drive it afterwards and put on a nice smoke show...anyone behind you will hate ya!
