Spray Throttle Body Cleaner

[alero_ecotec]

So, i found some throttle body cleaner in my garage today that i forgot i bought. Basically, you just disconnect the air intake after the mass airflow sensor and the filter, turn your car on, and spray the stuff in for 10 seconds while revving the engine, and then let it just idle for 10 seconds, it says on the label to use the entire can. However it was taking forever, so i used maybe a little under half. Has anyone tried this before? and most of all had any results? I didnt really notice anything, well, actually, i did notice that after when i was sitting at a stoplight my engine was so quiet i thought it died on me, but maybe that's just me. Anyone else have anything to say about this stuff? .........i kinda figure it's like fuel injector cleaner, it works a little when the stuff is really gunked up, but otherwise its a waste of money.
