try cleaning the idle control valve with brake cleaner,check the current of valve should be around 700ma to 1000ma also the voltage is around 4 to 5 volts. check for vacuum leaks especially around the fuel injectors seals get hard and leak use wd40 squirt around each injector if the idle drops you found vacuum leak.. stalling! fuel pump relay common problem.. EZL cutting out possiblity but if you replace this part make sure you install new ignition coil they cause the ezl to fail...this is just a few things to check
