Question about 2002 Kia Optima
Replaced the spark plugs, wires and the valve cover gasket due to bad valve cover gasket. Now the mass air flow sensor is bad and there is a loud popping noise coming from the engine. It almost sounds like a small fire cracker. Any input would be very appreciated.

There is a good chance it could be your fuel pump , however if the check engine light is coming on and the dealer cant tell you what is wrong , try a different dealer or another shop. Second opinions never hurt.

power steering pump probably went out.. if you can easily get at the belt and are any kind of mechanically inclined, remove the drive belt to the p/s pump and then start the car if the noise is gone then its probably part of the power steering pump
