1984 944 rough idle


Vehicle Information: Model(924/944): 944; Year: 1984; Engine (type, size, modifications): 2.5L, NA; Total Mileage: 132,990;

I read the posted answers to related questions regarding rough engine idle and misfires. It seems that several answers recommended checking the airflow sensor. Is this known by the term oxygen sensor, also? My problem is that my car runs fine when I first start it. After about only 5 minutes of running, it begins to idle very rough (almost like it wants to shut off, but never quite doing so). If I blip the throttle, it'll rev fine. It revs normal above 1500rpm. I had just changed the spark plugs (at my mechanic's suggestion), and it ran normal for about 2 days worth of driving, then it was back to the rough idle.
