Cleaning intake manifold/injectors
Hi everyone,
Has anyone actually taken the intake manifold off and had a look at their injectors for carbon buildup? I'm very interested to give this a go as there's plenty of guides on the mazdaspeed forums. I'm getting poor fuel economy lately and guess it can't hurt to see how bad they are. Would it be worth running some Subaru upper engine cleaner through before I take the manifold off or bother taking it off at all if I do this? If I do do this I'll be sure to put some photos up!
Thanks!
