93 Regal idle issue

[wellcare]

I have a 93 Regal custom with 3800 engine. The engine idles at a stop at about 800 rpm. At times it will idle at 1000 rpm or maybe 1200 to 1500 rpm. When the idle is very high I will shut the engine and restart, most times it will return to 800 rpm. I cleaned the MAF and this seemed to help as the frequency has lessened. Any help would be appreciated.

Clean the pintle on the IAC motor and also clean the bore and throttle plate in the throttle body......plate or IAC could be sticking....also check the opening and closing of the throttle plate in the bore for binding.....check the linkage too....
