High idle on "93" Lebaron
 

I have a "93" Lebaron convertible with 3.0 v6 & manual trans. Out of the blue, the idle will not go below 2,200 RPM. I have checked AIS & MAP sensor & substituted new ones with no change. No vacuum leaks. This started after I cranked the engine, it did not start. I think I just did not hold ignition switch long enough. Cranked it again & started right up but idle was high and idle will not come down. Any ideas?
