whats the differenece in doing both? i know that induction flush costs more, but i can get it done for free.

 

...or GM Top Engine Cleaner (Pn 1050002)

If it's free, for God sakes take it. The product (however) I haven't heard of here in the North East.
Sea Foam and GM Top Engine Cleaner are similar products. De-Carboning agents which clean the intake track and the Combustion Chamber of Carbon build-up. I've also used T.E.C. to free up stuck piston rings,

i dont' really understand...you mean GM top engine cleaner is the same thing as an induction flush?

 

What I said is: I'm not familiar with Induction Flush.
If, like Sea Foam and GM Top Engine Cleaner, Induction flush is drawn into the engine either by a convient vacume hose (or application machine), is allowed to run through the engine until it stalls, and then produces massive amounts of Really Thick smoke when restarted, then Yes they are the same.
