Rough idle, Stalling,hesitation.

[scissors4hands]

Alright so i have 89 single cam ka and recently it has been bogging down and dying. The idle is rough and there is a hesitation when it first takes off, and sometimes it just bogs down an dies an doesnt want to start.

i have two codes 13, 33.

things i have changed are the air filter, fuel filter, fuel pump, i cleaned my mass airflow sensor.

could it be bad injectors,bad mass airflow sensor?

i know one code is the 02 circiutry sensor, should i try to fix that an the other code then see what happens.

Any helps or tips would be awesome, and well appreciated.

i apologize if i have horrible grammer right now, im in a rush =)

Any time you have a fault code you should start by working on those. I don't remember what ytour codes mean but if one is the 02 then start with that.

Once you have fixed the car to the point of no code and things still are not right then ask again.

one of the codes was the "o2 sensor circuit" cant remember the other one.

edit: Wow, didnt read his original post fully.

replace o2, sea foam treatment, and find out the other code

Problem was my coolant circuit sensor,

so you might need to get a new one if you have the symptoms for further reference
