Something causing a misfire, bad battery to blame? Hey all, been awhile since I have posted, but I started my 02SS up and took it for a spin today, it has been in the garage for the Chicago winter and started it about every month.
Last month when I started it I noticed that the battery was dead so I jumped it let it run for 10 minutes and shut it off, today when I started it the battery was dead again, so I jumped it again let it run and took it for a drive, I noticed that the car was missing as I leaned into the throttle a little bit and it was a pretty consistent miss. Just out of curiosity when I got home I shut it off and immediately tried to restart it and the battery was cashed again, so clearly the battery is toast and I need a new battery.
My question is can a bad battery cause a misfire like this? When I put the car up for the winter it was running perfectly and really haven't touched it since, so I would assume it is just the battery.
Any help would be appreciated. I would like to start with the most simple like battery and eliminate from there.
Thanks,
Jeff

That's great, but why resurrect a 2 post thread from 12 years ago to tell us? @G Atsma Are you getting soft on these newbies? You'd normally have admonished them within 5 minutes of them posting, lol.

I was dealing with this a few weeks ago, took the voltmeter to a few spots and found the power from the alt to the battery was hanging on by a strand or two. Got that wire remade and life is good again! I thought a just had a old, bad battery at first

First of all, do NOT come in here and attempt to talk **** to me when you can't even spell. I've been a contributing member on this site for nearly 20 years, what have YOU done? The point is, if you have a problem with your vehicle, go ahead and search for the answer in the archive, but if you can't find it, POST A NEW THREAD. It's not that difficult of a concept. Pulling back old threads to present day just serves to muddy the waters for people actively searching for information.
