The car started stalling and it smell like something was burning. The car would shut off and restart on its own. I replaced the engine out of my pockets and now I am having the exact same problems. First before replacing the engine the serpentine belt broke and I had the repaired, about six month later a bolt broke inside the engine and that is when I replaced the engine. I just got the car back three weeks ago and now it is doing the same thing.
