Low Idle after plug change
So i just changed my plugs. It took about 10 rotations to start, like 8 more than normal. Now the car idles at 500 RPM. It seems to idle smoothly, rev fine and doesn't seem like it is missing. I don't think i got bad plug or forgot to connect the coils or anything?
I know some cars have a learning ECU, Does the subie? Since the battery gets unplugged i am wondering if it has to relearn the idle or something.
