Ok, well i bought my car about a month ago, and I was driving it like a week ago and I did something I shouldnt have but i was going like 3 and i put it in park not thinking and the car jerked forward and stalled and turned off. I restarted it and when i put it in drive it stalled exactly like if you dont give it enough gas going into first in a manual car. My car is automatic though. So I had my friend whos a mechanic come over and he got it moving by putting it in gear and giving it alot of gas. But its been 2 weeks since thats happened and right after I got done getting gas today, i felt it started to rumble in the engine and i knew something was wrong. So I parked my car and boom, as soon as I stopped the car stalled... What's going on with car? any suggestions are welcome.
