New here, 84 C10

[Jzaelke]

Hi all, new to the site, Just purchased a 1984 C10 pickup. The engine was rebuilt a couple years ago and some performance parts were put in. but it sat for half a year and I drove it home (about an 75 mile drive) And It died at every stop light. If I dont go over like 15 mph it wont die but anything over that and I have to switch to neutral and keep my foot on the pedal to stop it from dying. Im not to mechanically inclined and cant afford to spend alot to keep this thing running. I need to know where to start and what to look at first. Ill be posting pics up soon. Thanks!
