Hi friends
i bought civic a week ago and when i run the car and it runs 3 or 4 blocks it turns off. The revolutions start going up and down. It goes really low and turns off. But when the car is cold it turns on with no problem. Please i need help urgently. I was told to clean the negative wires cause it was something that cuts the ground, didnt work

Did this randomly start? Check engine light on?

The car starts but it will not stay on. When it shuts off i put the car on parking again and try to start it back up and sometimes it turn back on after to attemps sometimes it takes more attemps for it to start up. Yes the engine light is on.

If the engine light is on scan it for codes. That will help figure out where to go next.
