Hey folks, had a few questions. I just setup a ODM II reader in my H3, and ran the App for the first time today to see what it's all about. No codes or anything, so that's good. I did notice however that my RPMs are inconsistent (run between 590-610), and that my MAP is around 9.4 at idle, and is also inconsistent (goes from 9.4-9.7). My fear is that I have a manifold leak of some sort, but I have no symptoms as such (no ticking, clunking, coolant, etc.). So my thought went to a faulty MAP sensor. Just seeing your thoughts on it. For reference, it's an 08 with the I5 and just over 80k miles. New oil 2k miles ago, just cleaned the MAF and TB a few days ago, and new plugs a couple weeks ago. Other than that, runs great as far as I can tell.

Take a peek at your intake bolts. They've been known to be loose (or fall completely out).

The MAP sensor measures the pressure in the manifold. As your idle fluctuates the amount of pressure in the manifold will do the same. Your engine is running as it should so don't think to much into it.
