throttle body cleaning
I am fixing to clean my air filter and was planning on cleaning the mass air flow sensor and throttle body. I have read the how to guides here and they both seem like easy jobs. The thing is that my throttle body has a sticker that says not to clean because it has a protective coating that can be damaged. I know that it is dirty because I looked at it when I installed the kn air kit. That was at 70k miles and I now have 130k on it. Advance auto has CRCs maf cleaner, is that safe to use on the throttle body also? If not what should I use?
