car has a base tune and sputters cant figure out why. tuner told me to get all codes figured out before finish tuning. which i understand why!
did have this code till i changed out the ica
412 R Unable to control RPM during high RPM self-test
173 R,C Oxygen sensor indicates rich condition, right side
411 R Unable to control RPM during low RPM self-test
538 R Insufficient change in RPM

now that i changed the iac motor these are the codes
173 R,C Oxygen sensor indicates rich condition, right side
411 R Unable to control RPM during low RPM self-test
129 R Insufficient Manifold Absolute Pressure/Mass Air Flow change
167 R Insufficient Throttle Position Sensor (TPS) change
225 R Knock not sensed during Dynamic Response Test

A simple spark plug would put everything off. After I did my engine I had the same issues, make make make make sure you pull each plug and check for cracks... If its not that then good luck!!

well i went out there and cleared the codes drove it. acted up again.

pulled KOEO codes
111 System Pass
111

then KOER
173 Oxygen sensor indicates rich condition, right side
411 Unable to control RPM during low RPM self-test
538 Insufficient change in RPM
173
411
538
then the balance test
9 Passed Cylinder Balance Test
9

car isnt fully tuned. i still need to get my wide band o2 sensor(to finish) and im still waiting on the mp plenum.

i just wanna make sure its just the tune that needs finished and that it isnt the car having issues.

thanks!
