I realize there are several threads on this issue, but couldn't find one with a definitive answer (as if that exists), and didn't want to hijack an old thread. I also asked a similar question before but wasn't able to find a solution. I'd like to know if I'm on the right path here.
Recent fault code: p0507
Problem:
Back in January I replaced the spark plugs, cleaned the TB and MAFS, replaced PCV valve, new engine air filter, added half a bottle of seafoam. After this, the idle went wildly high. It pulls me forward when I release the brakes. It will speed up to 15mph from a stop way to fast. It does this in reverse and drive. It doesn't normalize when warmed up. I've done the manual TB reset protocol I found on here twice with no change. I don't have a OBD unit that can reset the TB. Others on here said reseting the TB was unnecessary as it would normalize over time. Iive since driven 4500 miles with no change at all and has not normalized on its own. Still idling 1100-1400 at rest. If I'm crusing at 40mph and release gas, it barely slows down. It has become almost dangerous as it will push me into traffic at intersections or parking spots quicker than expected and I need to quickly apply brakes.
I noticed it feels like I need to depress brakes considerably more than expected and brakes were brand new 5000 miles ago.
As i went through the thread below, it notes a vacuum leak of the brake booster (or hose) like should be checked. I'd never heard of this. But it sounds like a reasonable place to start given the braking issue?
Is there a best or most doable way to check for these vacuum leaks if I don't have a smoke machine? I haven't really yet found a good way explained.

As well, others have said not to manually open the TB when cleaning... I did that. How can I test if the TB is the problem before replacing?
Any other thoughts or threads on this are appreciated.

please help with code P0507, P2279
i have a 2007 honda odyssey and i dont have any issue with my engine. since its already 115,000 miles, i thought of adding an additive to improve the engine performance ( cleaning the carbon, injector and upper cylinder, etc ). i bought an additive called SEAFOAM and pour some (1/3 as directed)...
