Answers :

Could be many things but it sounds like your idle air control valve. It should be on top of the throttle body. I'm not sure on this vehicle. It is a accordian like diaphragm in a housing, They get clogged with carbon. Usually attached with 2 bolts and a sensor connector. Easily cleaned out with carb. cleaner. This will throw a code if the diaphragm is letting too much or too little air in to the fuel mixture. It may also be a vacuum leak. You can spray very short burst of ether around the intake manifold, if the engine races you have a vacuum leak. I have never had a fire but have always had a fire extinquisher within reach . USE COMMON SENSE.
Good luck. p.s. DON'T SMOKE AND KEEP CHILDREN AWAY!
