My car sounds like it pops when I accelerate. It is not running right. What is wrong with it?
You could have a bad fuel pump. I would recommend to check fuel pressure. Fuel injected cars are very fuel pressure sensitive. Fuel pressure is very important and must be within specifications! But if the pressure is low, it does not mean the pump is bad. A plugged fuel filter, a pinched line, and low voltage at the pump can contribute to low fuel pressure. Both must be checked before replacing the pump. You can get a fuel pressure gauge at a local auto parts store for cheap.
