Few days ago I had to replace my Scooby's old battery after more than 2 years of faithful service. I bought new one and after less than 5 minutes work time everything seems to be OK.

But .... since the replacement the engine idle speed seems to be wrong.
When stopping at a traffic light the engine stall and I have to restart it.

Any idea what went wrong and how should I fix it ???

 

I'd agree with Andy - I took my battery off for a recharge and had the same for about the first 20 miles then it settled down OK.

I was disappointed to find my MY98 hadn't got a sealed battery, it's one where you have to pour water in (nope I didn't take 2 years to discover this, have only recently got the car).

I'll be changing to a higher capacity sealed unit sometime in the future.

Sounds very strange !
I'm not sure that replacing the battery could lead to a problem like this
Could it just be a coincidence??

Just a thought!

If you reset the ECU by disconnecting the battery. And the ECU reset actually works (I'm sure some will disagree) then that's what you've done.

In which case, just drive the car as normal until the ECU re-adjusts the ignition/fuel settings.

I'm guessing now, but you may find the problems will clear up as you drive the car more!

If I'm wrong please correct me, I'm just making a lot of assumptions in this post!!

I just spoke with a technical guy from Subaru in Israel and said something about that it's a well know common problem.
According to him all I have to do is "reset the air flow meter".
Any comments?
