What is the LS supposed to idle at while in park and at a stop while in gear?


I have been running into issues with a slightly high idle and the dealership kept telling me that it is do to the K&N adapter but I didn't buy that.

Anyway I keep up with oil changes and air filter cleaning on a regular and I changed the fuel filter not long ago.


Yesterday I cleaned the MAFS with the proper agent from CRC as well as the sensor ( what is it ) after the MAFS. I let it dry over night and started it up today. The idle after it started was around 1,000 or just above then slowly without fluctuations or anything odd it went down below 1,000 and was so smooth and solid. During this idle situation with my exhaust being upgraded you could notice something funny going on with the idle while in park and was always just above 1,000 but now man it was just straight flat and smooth!
 
When cold 1,700 +/-, after about 20 sec down to 850 +/- and when hot 850 +/-.
 
Cool!


It was sticking around 1,700 and surging slightly but now its down around that 850 mark.


Thanks!
