I have a clunker that's been sitting for ages(1year). It wasn't starting right but after boosting it , and running for hours it seems to stuter a little but start up(Only been two day s). I have a dura battery charger with an inflator combination. One of the tire was flat the first day. So we put in slime inflator. Than pumped it up. The next morning the back left went flat, {free a snow storm of 13"-15 and freezing temperatures.{ Still freezing} I went to put air in the back tire. I see no sign of tear. Although it is very cold(-3) so I could barley check. The PSI rating stayed at zero for 30 Minutes. My downstairs neighbor says it's too cold out , to wait for the temperature to rise. I took the charger in for the night. Checked the car this morning. Stuttered a little bit, but started right up! Also the battery icon that showed up before it would start has disappeared. [{ Went to place of purchase yesterday with mother to check and the battery was bought almost 2 years ago. Tobecon..

My car has 194000 miles.
My car's transmission is unknown to me.
