I've read the how-to and the forums, and even more confused. I want to do this right the first time, so please help!!! First should I do this to BOTH the vacuum lines behind the MAF? Is Chevron injector cleaner good to use, or is there something better? Should I use half the bottle on one then the other half on the other vacuum line? Also do I need to rev the engine past 4000 rpm? There seemd to be 2 sides to that story. I have tried in the past to remove the vacuum lines that plug into the manifold, I assume these are the lines I need to unplug, and never did get them off. I was afraid of breaking them. Can I go to the other end of the vacuum line to feed the cleaner? Thanks, Thom
