1992 Plymouth Laser

Engine Mechanical problem
1992 Plymouth Laser 4 cyl All Wheel Drive Manual 117551 miles

1992 gsx plymouth laser. All wheel drive turbo. My car starts up with high idle. After about a minute the idle surges up and down real rough. If I don't keep it running giving it gas, it will eventually die. Driving, it runs fine until I come to a stop, then it will stall out. I'm also getting really bad gas mileage. A full tank got me 150 miles or a little less. I've read on forums about these cars. A lot of people said the idle speed control module is known for going out on these. I can't find that part anywhere tho. What do you guys think my problem is?
