ECM Idle learn

So after many issues with my car, i finally found that the ground cable to the body was simply loose. after cleaning and re-connection all connections everything works beautifully! only problem is the ECM is having some troubles learning the idle speed. as you may know, i'll be driving, then i'll stop at a light, and the idle will go up and down, almost stalling out. then it finally evens out at a very slow speed. I was wondering if theres a certain procedure for learning it so that i can just drive and go, and not have to let it idle for weeks. thanks!

Just keep driving it it should have relearned by now.

yea thats what i thought would happen, but everytime i stop at a light or a stop sign, the RPMS move up and down, almost stalling the engine, I found something online saying to leave it in drive while holding the brake, at operating temperature, i did that the other night in my driveway when i got home, and since then, no problems.
