1994 Ford Ranger • 200,000 miles

When I started my truck this morning it started up fine and then it made a popping sound kind of like when you let air out of a bag. Then it began to shake and rough idle and slowly begins losing power. A few hours later I started it up again and it did the exact same thing except the popping sound. Do you know what the problem might be and how much it will cost to fix? Thank you. Jamie

Clean the idle air control valve and also the MAF sensor with an electronic cleaner and see what happens-inspect air intake tube between the aircleaner and throttle body-
