The main CPU component failed in my car and grounded out the second cylinder causing a fire to happen, This happened on my way from the store while I was in traffic and almost caused me to get into an accident. Luckily no one was hurt but now my car is not functional. I took it to a mechanic to see what the cause was and that's what they said it was the computer that failed and that I would need to take it to a dealership in order to have them fix it. When they asked me when I started noticing the symptom I said it started happening a couple months ago there was a random misfire check engine light that came on. And then this happened. I'm desperate please help me.
