So my '94 is idling a bit rough & CEL is on. Sometimes it goes off while going down the highway or idle, sometimes not. Cannot find any parts chain that reads OBD1 (Only OBD2). I decided to check the code with DaRoch's link. Paperclip between the two connectors & I Get

Says Mass Airflow sensor according to the list. I had the thing out & it is clean. The wires were not broken. Trust me, I was looking at them with a 50x digital microscope at work.
I then tried to do the test with the engine running. I did the above, then after the 2nd 157 I started the engine. Now I get
998

Before I go & sock $$$ into this, can someone tell me if I did the right thing & diagnosed a bad MAF sensor? Can I buy the sensor alone without the body? (Autozone & NAPA both show a complete unit)
What else should I check? Power plug for the sensor? How?
Any ideas??
Thanks in advance
