its nothing big but im just wondering as to what it could be. when i rev my car up to 4k rpm's and let it come back down the rev's will drop down to 100 and the car will struggle to stay alive, and than they come back up to about 800ish and bobble between 600 and 800 for a couple of seconds and than idles smooth. anyone know why it could be doing that?

I had the same problem on my JDM NA supra.
It turns out the the hose to the map sensor, was at the tip cracked, adn when I rev up the car the car was trying to stabilize the idle
