Q: Compressed air noise followed by smoke.

After jump starting the car the engine started making intermittent hissing noises, they sounded like blowing compressed air, from under the passenger side of the engine. A fine smoke came up followed by a burning sell. Smelt like burnt rubber/plastic. The check engine light never came on before or after. What does it sound like is going on with my car?

My car has 89000 miles.
My car has an automatic transmission.

Hi there. From the description you have provided, concerning jump starting your vehicle’s dead battery, there may a combination of problems. Smoke and a burning smell are not good. First, I’m lead to believe, the battery has completely failed.
