If you smell gas through your air vents, then your engine is burning too much gas which increases the amount of gas fumes coming out of your exhaust. This problem could indicate that you have a failing fuel pressure regulator. Here are the other symptoms to look out for:
  • Black exhaust smoke
  • Engine misfires
  • Poor acceleration
  • Stalling
If you notice the above, you may need to replace your fuel pressure regulator which can be expensive. Luckily, you can save money by using the Jerry app to shop around for
