My check engine light keeps coming on. At first it would go off and on with no code. Now it stays on with the code p0420 for the catalytic converter. Also I heard about an air bag recall.
Oil was low check engine light came on need new engine said it was from metal shavings in oil.
I came to a complete stop and proceeded to turn left when I noticed the check engine light came on and as I pulled over there I noticed a thick cloud of blue smoke out of my rear view mirror. I opened the hood and saw flames at the back of the engine around the transmission and airconditioner area of the car. Flames continued until the interior began burning and windshield broke.
