so when my car sits a while like 6+ more hours i go to start it. it seems like it stalls to start. it will try to crank and sometimes not turnover. but most of the time it start up. i have the demon coil pack could that be going bad? i just change sparkplugs so that not the problem.

 

Your battery might be bad.

 

battery was just replaced 1 year ago. im thinking it the coil pack itself. im going to try my stock coilpack this weekend or starter idk
