Rough idle

My car is a 2005 chevy aveo it. Stalls out when take off oil light blinks off and on what could the problom

Almost sounds like it's missing. Have you changed the spark plug wires? I would pulling by one answer if you notice a difference. Could have a bad wire. Sounds like a timing issue.

Yup. It chugs a chugen

Does it cost alot to fix

New cap and rotor?

Pull your cap if you not changed it. Check inside it. See if you see white lines on the inside. Best describes and white lightning marks. Could be bad cap that's causing a misfire.

I bought the car off rightway. 5 months ago still maken payments

Sorry I was answering the questions. Above for this forum. But have you checked to make sure you have oil?

My rule of thumb is always check fluids and change oil when buying a used Alvarez that is not certified.

Ok i will do i just checked it and added a qt of oil

What cap and where is it located

Pull throttle body, easy to do, clean w/ carb and choke cleaner using a nylon brush only. Makes a hell of a difference.
