Hey Guys,
Have an issue with my new legacy.
Starts up and idles fine, until it warms up. I notice it most when pulling up to lights or after coming off motorway. Idle will drop right down to just about stalling (will cut out on occasion), will then idle real low, like on the brink of cutting out, sounds like a lumpy cam almost.
Have no check engine light on, but it has some stored. 12, 21, 23, 32. If the check engine light is not on does that mean the sensors are fine. Or could it be the water temp sensor, the air flow meter or the oxygen sensor from the stored codes? Check engine came on once after a really long uphill thrashing on the way home, then went off so guessing that was the ox sensor one?
Car has a BOV fitted and have read this can cause idle issues also.
Any nudge in the right direction would be awesome, can troubleshoot and have worked on cars lots. But my first Subaru so any help appreciated to save tail chasing if its something obvious\common issue with these.
Car is manual with an EJ20R.
Cheers.
