Help Save My Car

Hi, i am in desperate need to fix my car. I am a single Father of a teen in Colorado. I lost my job due the Pandemic and am currently on Unemployment looking for a new job. My car recently sprung an oil leak and was ran on very low oil. I was able to leak to stop but now my car is having a hard time starting and when it does, it misses and struggles very bad. I need yo fix it because I am still making payments. I spend my unemployment on rent, utilities, food and my car payment so I dont even have the money to get it checked to see what the issue is. Please help me save my car? 
Thank you.
