you may look into what is called a throttle position sensor. it basically monitors the position of the throttle and tells the fuel injection what to do. if it goes bad, the car will stall and won't run unless you give it more gas to keep the rpm's up. the throttle position sensor is typically located on the side of the throttle body, right near where the air intake hose joins the engine. they are relatively inexpensive , available at any car parts store and easy to replace.
==========================check: 1.idle speed adjustment screw, 2.vacuum leaks, 3.ignition timing,4.carburetion problems,5.emmision vapor charcoal cannister clogged,6.dirty fuel filter,7.fuel pump not working right,8.dirty air filter,9.pcv valve bad. ================== On the back of the carb is an idle stop solinoid that shuts off the air flow through the idle passage way. I have found that the passage way can be blocked with dirt. Remove the solinoid and spray carb cleaner in the solinoid hole then blow out with compresed air. Be sure that the rubber O ring for the solinoid comes out with the solinoid and is not stuck in the hole first. Also check that there is 12volts going to the solinoid when the key is on the run position. This is somtimes fed through the alt. fuse.
================= Loose Hot Wire to control box for electronic controlled Carburator.
