I saw a video on YouTube of a mechanic spraying CRC GDI unto a really carbonated BMW turbo engine directly unto the valves. I saw the product started to bubble up and dissolve the carbon. It must be really effective stuff!!! I think I'll do it before each oil change. I heard nothing but good reviews from knowledge people. The only negative reviews involved inproper application. You have to spray it AFTER the MAF sensor.
That said where is the said vacuum line?
Would be better for me to post a pic later
