2010 Kia Rio5 misfire Sign In

I have a 2010 Kia Rio5 1.6L 83000 miles.
My Kia Rio5 has popped up three codes.
P0300
P0302
P0301
The car is running very rough but i put in gas and it made me not move. My car stalled and I was stranded. I then turned my ignition and my car started but stalled again. I then turned it again and gave it some gas and was not moving very fast maybe 2 MPH. I got home but after I let off the gas it stalled. I cleaned the Mass Air Filter with the spray but it is still giving off the same codes. I need to know what to do.

Those are misfire codes. Misfires will cause loss of power and a rough running engine. Did all these problems start right after you filled up the fuel tank?

There are some things you need to figure out. First you need to find out which cylinders are misfiring, but the engine has to be running to do this.

The misfiring could be caused from an ignition, fueling, or mechanical problem in those cylinders that are missing. There are tests you can do to figure that out, but if you have no experience in diagnosing misfire issues or don't know how particular systems function, your going to have a really tough time figuring it out.

You may need to have it towed to your repair shop that has the equipment and trained techs that can determine the cause and fix.

i was wondering if i should get a compressor tester and check the pressure in my engine. I also have no idea where to find out where my fuel filter is for my car

You can do a compression test. You have to disable the ignition and fuel. The throttle has to be open and the battery has to be fully charged.

Fuel filter is part of the fuel pump assembly in the fuel tank.
