hey guys, i have a 2000 mustang V6 and its been having troubles starting smoothly. it always starts, but after sitting for the night, when i go to start it in the morning it shudders really badly. its not the starter or anything like that, i was thinking it was maybe the idle control valve? or something to do with the intake maybe? im not sure. any ideas?

 

mine did this, it was with the stock battery. do you have an stereo hooked up? i got me a new battery and it's good now.

 

yeah, i have subs, amp, and head unit hooked up. just get a new battery? ill have to try that asap. thanks.
