What is p0800

What is your question?

Veh is not mine. One I am considering buying, 198k miles. The CEL came on 3 dys ago. Code p0800 was pulled, misfire in #8. It is an '09. I own an '09 Z71, now with 196k miles. And was looking for a family veh. Have been a Chevy man over 30 yrs. Any help suggestions would be awesome!!! I'd be able to buy it outright. But would not want to throw away money either. I have a '16 Prius as well. So the thought of those economics with passenger room & towing ability is my goal. THANKS MUCH IN ADVANCE!
