Check engine light does NOT come on AND car cutting off

What is your question?

I have a 1997 Nissan Sentra and the check engine light will NOT come on. Sometimes the other indicator lights work, sometimes none of them work. Any help ont his would be appreciated since it will not pass inspection for NC without the check engine light working properly. Also, my husband was driving the car the other day. He stopped at a stop sign and the accelerator got stuck, reved the engine on its own, then cut off. He cranked it up and it was fine. Well, today she was driving it again and the car started loosing power around 45 mph then cut off. The engine is NOT knocking, has 124,000 original miles. No noises heard. After a few tries, it cranked back up and he was able to drive it home. Any ideas?! It was checked and he does not remember what the code said, but it said something about air flow and spark plugs. Thanks so much in advance!
