Default Limp mode maybe?

Hello! I have an 86 base vette, it’s my first vette and car that I’ve ever worked on. Today I was driving home from work and I gave it a bit of beans to pull out into traffic and alittle bit into that as I was getting up to speed for the highway I lost power and had very little after that, I managed to get home but I couldn’t go over 35 and any more then a slight push on the throttle I’d lose power even then it almost died and after the it would lose power and speed and almost stall out. It starts up fine but idles almost smoother but faster then normal. Please help

Limp mode basically means that the ECM is running the car on default tables because a sensor or sensors are not functioning properly. Possibly a bad MAF?
