88 5KTQ this week my idle speed has gone up

Hi All
I have an 88 5KTQ this week my idle speed has gone up. Normally and now when 
I first start the engine it idles at between 900 and 1200 rpm. Now after the 
engine has warmed up it idles at about 2200 and then goes down to about 1800 
rpm. I have checked the throttle and cruse control cables and they are not 
holding up the idle. What will cause this?
