UPDATE. She is running great now. it ended up being the 2 bolts holding my intake manifold on. i noticed when i did the injectors that they were loose and stripped out. they just wouldn't tighten. i ignored it cause the intake felt tight. i went on to clean every connector and every sensor. i clammed all vacuum lines that were missing clamps. was slowly getting better but still not right. so i went old school and started the motor and sprayed carb cleaner near where i had a feeling was the issue. and she idled up every time i sprayed the area. then it started to hiss. so i took a hose and listened to the area to pin point it's location. it was the gasket leaking. i managed to find 2 bolts that worked perfectly and now she is running great. now i am waiting for my gas tank i found and also finally changing my suspension. got new tokico shocks and lowering springs. thanks to all of you for your help. you guys keep me driven.
