97 Oldsmobile Bravada 4.3
I finally got my misfire gone on the Bravada (I hope). However, it has been a little sluggish and I think it is time to clean up the upper cylinder/combustion chamber to get rid of some carbon. I have a watched a few video’s on how to do this and looks pretty straight forward.
Only problem: I think I grabbed the wrong stuff when I stopped at the parts store tonight and grabbed Berryman’s B-12 Chemtool fuel treatment (Pictured Below). Do I need to get the step 2 combustion chamber cleaner instead? I am running this in the brake booster line, the crank case, and the gas tank as shown in the DIY video’s on Youtube. Not sure but I think the Berryman’s B-12 Chemtool may just be for the gas tank!!!???
*Also going to put on a new fuel filter. Should I add the new fuel filter before, or after I do the flush? I am thinking after – and even after I do the driving to run out the deposits/smoke from the flush.
Thanks!

Well i would consult your local parts store about whice to use but on the fuel filter wait till after the flush if your putting things in the gas tank it can stur up sediment in the gas tank and possibly reclog the filter and maybe do a little more research better safe than sorry good luck!
Honestly I don’t think that will do much good. More info on solving performance problems here.

That said, all you really need is to inject water into the intake after the engine warms up while holding it about about 2500rpm. Steam cleaning is the best decarbonizer I’ve ever seen.
