im currently in the process of doing a fairly major tune up (changing plugs n wires) replacing 02's, recharging AC, flusing coolant system, replacing fuel filter and runnin cleaner thru injectors...etc. So i thought i would pick up this b-12 chem stuff i saw at walmart. it says it cleans the pcv and what not, but what else can i clean with it, can i clean out my throttle body with it, what else should i do with it to help my car? thanks

 

You can clean your TB with it, but I would take it off the intake manifold. I think it might damage your O2's, and eat some gaskets. I used it to strip the grease off my intake manifold, heads and valve covers...it worked well...again, though, all were off the car. Don't get it on anything painted, it will eat right through.

Long and short: anything metal coated with oily gunk.
