Re: Reset the computer after changing the battery ?
You will have to drive it to do that. If you do not have a scan tool go to Advance , auto zone or pep boys they will tell you for free. You do not reset the computer it has to relearn itself

I assume that you are saying that the car idles poorly, after you changed the battery, and you are requesting information to reset the computer.
There is no 'reset' button., What you have to do is drive the car, about 5 miles, in stop and go traffic, and then highway speeds., This teaches the computer the 'base idle parameter'.
Drive the car, as described above, and your base idle will then readjust itself for optimal performance.
You'll have to reset your clock and it will reset the computer in the car but you'll be fine. Just remember, black to negative and red to positive. Keep them straight and you won't have an issue.
Also, parts stores often change them for free if you buy the battery. Napa, Auto Zone, Advance Auto, etc. If you're that uncomfortable.
the computer is reset by just removing the battery and let it sit for about 10 minutes then just plug it back in but i think your terminals might be dirty scrub them and plug the battery cabels back and started
Did you change the Batt right before the emissions test? If so bad idea. Yes the car needs to be driven for some time before the computer sets up timing fuel and spark carrectly. Drive some more then try the test again, should be ok and pass
