so i this past weekend i got my car out of the snow bank and got in in the garage let it **** over night warm and thaw out. so the next day i put the battery in witch is fully charged i turn the key and nothing just clicking and killed the battery right away.so i check all the grounds got power to the starter. so i charged the battery again cleaned the battery posts and tried again same thing didn't turn over just click then battery dead. so now i boosted the car and it idled at 3000 even with the throttle cable of and when you give it shot of gas on the tb it stays at where you rev it example you give a shot to 4000 stays there and wont go back im not sure what would really be causing this any thoughts ??
