Kia Rio: Engine light Flashing P0300 P0301 P0303 

Just got our kia(same issues and codes) from the shop. Ran great for 15min going home, then it popped a new p0302 code and started running rough. This video was very informative. Going to take it back to them asap.

Yesterday my 2011 Kia Picanto ony has 3 cylinder and was exactly like this video, my mechanic on the phone who has replaced the spark plugs last month to iridium bosh, right away said it was one of the coils and the engine is misfiring. this video explained it to me very well. thats good to have a brother in law as a mechanic and eletronic auto specialist. great video, right to the point. explained very well to a non mechanic like me :) regards

Thank you for excellent troubleshooting video upload. My wife's 2008 Rio is acting up recently and I am going to work on now. I will update later.

Thank you Will. Good job again. Have a blessed and safe week to you and your family.

Nice to see you making videos again! I enjoyed this one! Although I enjoy any videos with a scope being used lol

Good to see another video from you!

freakin awesome misfire diagnostics!!! and fix

Well done as always! 👍

Thanks Will. I like the way you look at all aspects of the problem and not just dive in here or there. Looks like you fixed up a nice shop to work out of too. Stay safe Bill

Well done, Will. I like how you present the various different diagnostic paths that can be used.

Great video. Very informative

Nice job Will!

Thank you Will

Did you get to rebuilding the 5.7, been waiting. Best regards Gordon

Well done.

great video. curious what you charged for that work

tenks idol

thanks alot

Did you replace the coil?

You don’t utilize Mrs. Robinson to help you anymore?

these is how a one hour diagnostic charge can be turn in to two by pulling fuses on a fuse that provides power to all coils

nice job Will do you have a COP wand? thanks for video

I have a question I have a 2008 Kia Rio automatic transmission and my Timing chain broke and it bent a few values and broke one I had a shop fix all that and when I got the car back the check engine like would flash then stay on and it would feel like the engine is rocking back and forth so the shop replaced the coils spark plugs replaced the head gasket cause spark plugs was getting oil to them. The code the car is picking up is Cylinder one miss fire no other codes so the shop told me it was the fuel injections so they all was replaced now they are saying it is the computer. The car runs really good and only acts up when it's cold out. The car never had this problem until the timing chain was replaced. My question is do you think it has something to do with the replacement of the Timing chain cause under the oil cap it is milky and the shop says that is normal and if I take the Ignition coils off of the spark plugs there is oil on them. Could the shop that took care of my head have missed a thin crake in it. Every shop I ask won't tell me nothing they say take it back to the shop that fixed it. Can you PLEASE answer my question.

I’ve changed my spark plugs and all my coils it no longer has a rough idle but the check engine light is still on any suggestions?

👍🏻👍🏻👍🏻

I have a kia seltos 2021 and recently star sounds exactly Is sounds that kia rio and when i conect the scaner immediately give me a 3 codes whit miss fires for the three first pistons and i have only 80k miles

I have a misfire in num 4 cyl in a 2007kia rio. Switched coil packs 3 and 4 and misfire was still in cyl 4! Replaced all injectors with new ones no change! Removed and cleaned throttle body and throttle position sensor and still getting misfire in #4 cyl.! It runs way better since cleaning throttle body but still have the original misfire in cyl 4! All coil packs seemed to be fine and no oil or anything down in the wells. Not sure what to do next!

I have a question. So does the car need a tune-up & possibly new coils?

so all u did was change the plug wires?

Its funny all the auto channels i watched SMA, Scannerdanner, you and many more rums that d#mn fix it ad. I hate that freaking ad and they should be sued for misleading auto owners. There is no scanner in the world thats going to tell you whats wrong with your car. It can lead you in a Direction to test but, sometimes thats wrong. So how can that miracle 50$ fix it scanner tell you exactly whats wrong. Ive diaged cars that the repair had nothing to do with the code it set. It really gets me heated.

Where's the fuel injector rail in this car?
