Maybe your ECU sensor is bad, its not giving enough oxygen for your gas ratio, which makes it have to run at a higher speed in idle. Its highly unlikely that your throttle cable is bad, if it sticks your rpms wouldn't go down when you let off the gas, so its probably your ECU sensor, but the best thing is to probably adjust your idle speed down to 1000 first.

you just need to adjust the choke man, but never reset the ecu, do that and you **** up all you emissions codes, sensor, etc. do not touch the ecu

try cleaning the IAC control valve( its located on the throttlebody) using carb cleaner. then if that doesn't work try adjusting the IAC valve at idle speed(between 770rpm and 820rpm). last u might have to replace the valve. Also look for vaccum leaks, check all hoses.see if the throttle body cable needs to be adjusted. coolant temp sensor will probably throw a engine code(see if u have check engine light on and use a scann tool if nessacry). i hope this helps
