Ok well i changed my intake pipes and i changed to new hoses that we installed the bristles into but not the restrictor. And since then i noticed a slight miss at a steady rpm around 2000 after a cold start and then maybe after about 5 mins of driving it would be gone. Well then a month or 2 down the road " a couple weeks ago" i was doin about 80 on 295 and my z just shut off. So i pulle over and i thought the cas plug fell out cuz the clip is broken from the engine swap. So i pushed it in," it wasnt even out" and it started right back up and went about 5 ft and died again. Later we found out the ecu stopped controlling the fuel pump. so Luckily i had an extra one from the swap so we put it in and everything was all good. Well now that slight miss is all the time when not accelerating. And im running extremely rich. And when i accelerating it stumbles a lil. Any ideas lol? Could be that hose?
