Use seafoam on my 06 silverado to clean out top end of engine. Use vaccum line to suck in to engine. Can this be done with the ls? It turned off the engine lite on my truck that was giving code saying the o2 sensor needed changing or was dirty. The same is going on with the ls. I have a 3.9 and I'm not sure where the vaccum line is any help would be great.
