the main f.i. computer runs the idle valve but problems are usually related to input signals.common one is the fuel shut off microswitch mounted on the throttle linkage under the aircleaner.check and see if the plug has slipped off. the eha just needs to be replaced.unless one or other of the o rings under it leaks,replace it.
