Customer Question

02 kia sedona code po175

Hi. P0175 can be caused by too high of fuel pressure from a faulty fuel pressure regulator. You can check fuel pressure with a gauge. The code can also be caused by a Mass Air Flow Sensor. You can try cleaning it or just replace it. Please let me know how you would like to proceed. I have more info if you need it. Thanks. Please respond to let me know.

what could be causing this misfire , have spark at plugs this is a 02 kia sedona thank you
Expert:  EricFromCT replied 2 years ago.
The spark plugs can cause the misfire, the ignition coil or wires can cause that has well. Or even a fuel injector. You can start by swapping plug wires around and see if the skip changes to a different cylinder.
