Hi. You need to clean the Mass Air Flow Sensor.
This is an easy job.
Get a can of throttle body or brake cleaner spray at your local auto parts store.

Open the hood, and locate the air filter box. follow the tube from the filter box towards the engine. Look for a small black box with 2 screws holding it to the air tube, Remove the wire connector and observe inside the sensor with a flashlight. You will see 2 small wires, and they will appear fuzzy or dirty. Spray the interior with the cleaner until the wires are nice and clean. Do not use compressed air, you will damage the sensor. Put it all back together and drive it.
This will def fix your issue. This is a vey common problem. If you do it yourself, you will save 70 + bucks.

Thanks for choosing FixYa, and a FIxYa rating for my assistance would be greatly appreciated.

there are 2 vaccum hoses going into the intake. the larger one on top has a spring clip holding it and if you look under that you'll see a smaller one with a check valve. mine was disconnected. plugs in under the larger one.

You're not getting enough fuel. You should check your fuel pressure. If you have enough fuel pressure, your injectors are probably clogged up. Run a lot of fuel cleaner through your tank when you put gas in and see if it makes any difference. Lucas fuel treatment is the best to use.

You most likely have a big vacuum leak. PCV hose split or a bad Idle Air Control motor (IAC)

Testimonial: "i will try that thanks."

Before I bought the Mass Airflow Sensor, I looked up the codes again for the 2007 3.8L Kia Sedona. One listing was "massive vacuum leak". I took all the hoses and debris collectors off of the engine, and upon close inspection; the large air hose that connects the air filter to the intake manifold was dry rotted at ALL the ridges. I flexed the hose a few times and saw where the vacuum leaks were occurring. I also removed the EGR hose for inspection and found the hose was faulty as well. Since these parts are "dealer only", I used duct tape to seal the leaks as a temp fix, filled the gas tank and used fuel injector cleaner. Disconnected the neg. battery terminal, reset the codes, and the check engine light turned off. Runs like a champ now. Vehicle has 119,000 miles so I guess wear and tear like this is to be expected. New hoses from online parts dealer totaled 130.00. I got off easy I think.
