I have a 98 civic LX 5spd.

I disconnected my battery the other day, had to get it
tested.

Question 1:

What is the procedure for reinstalling the battery? My
Haynes manual says run the engine at 1800 RPM or something
like that for 45 seconds. Is that true?

Question 2:

When I did this 'run at 1800 for 45 sec' and let off the
gas, the idle was REALLY low for the first 1/2 hour or so.
Would this be indicative of a further problem somewhere,
and my ECU is compensating for it by running rich? (IE am
I losing fuel economy, but the ECU is covering it up by
adjusting the FA Mix?)

I average about 33MPG (US gal) 50/50 highway/city.

Thanks
