Self Made
hey everybody, when i bought the car the battery was run to the trunk, the posative lead was hacked up in different sections. anywho. i assume the battery is bad for starters, needs a decent jump to start. sometimes when its turning over the car starts super hard and sometimes does a little clunk-bang-pow, with a little backfire.
starter seems like it could be healthier could that be the root of the problem. im assuming the previous owner never replaced it because of the signifigance of the job
also the car is modded and untuned
thanks, jason

i could take a video if i had to
