It detects detonation( pinging) and retards the timing to keep it from damaging the engine.

I had the same problem with my wife's 97 F150. After my wife's truck died a few times at the light with such a low idle, I called a Lexus mechanic friend. He told me that my idle sensor had to be reset. I un-hooked my battery for 15 minutes, then re-connected it. Drove the truck for 15 miles, now it idles the same as my 2000 F150. Never a problem since. He said you must drive it 10 to 15 miles and he was right...Good luck.
