Subaru Legacy GT 2.5 AT
Engine runs uneven, idle speed is not regular.
Changes already made are the following: sparks, cable spark, coil (bobbin), IAC valve, oxygen sensor (primary and secondary).
injectors mesurments are ok
All technician here said was the motor computer, so I change it, but the problem persist and steel runs uneven.
History: At the begining the engine runs with a loose of power, but when sparks and spark cable were change the power problem desapear. But idle seepd still irregular and engine also runs uneven.
Computer error code: Primary Oxygen sensor.
That is why primary and secondary Oxygen sensor and Computer engine were change, but this error code persist.
Also mesurements were made on primary sensor Oxygen on 6 cables, and 4 cables on secondary Oxygen sensor, all tested ok.
VIN number : 4S3BE64581 7201026
Please your kindly help cause I do not know what can I do with the run engine uneven and irregular idle.
Thanks in advance,
