.. start it up to see how it is for a bit.. not so good.starts great but runs bad... it wont idle and it jumps .. and the engine runs just shakes and cant idle... also smokes black... only thing i havent connect was the brake booster to the intake... since i check the tcp and the maf. it all seems fine but still runs rough. maybe the air circulation. if you guys have any clues lmk. this thing just stressin me out
