My Kia had the Check Engine light On But it was working okay now it started to give me a little trouble

1.When I am going out an intersection and I try to give it gas it tends not to have any strenght or it cuts off.

2.Now Couple days ago I was going to pickup my kids from school but I had to make a quick stop, and when I got Back it wont start.

I got a code reading and these are the codes I got P0172,P0101,and P0123.

Can anyone give some HELP PLEASE

If any codes relating to injectors, O2 Sensor, Coolant Temperature Sensor or Mass Air Flow Sensor are stored, do ALL REPAIRS associated with those codes before proceeding with this troubleshooting tree.


.. at first do not jump to conclusion of changing all items related to codes. Corrosion at sensor plugs is common.
But let us have some more info, year, mileage, any repairs done before, previous troubles....some problems can have different meaning depending on age and mileage. FOr how long did you have the CEL ON? DO you have a scanner or had the codes read elsewhere? Were the codes cleared ? DId they come back and in what sequence?
