Ok I have been here before. Still ain't easy making mods and getting car to run right. I have a 86 gt mass air, stock bottom rebuilt, blower cam 1.70 roller rockers, aluminum Canfield heads, typhoon intake,, 30lb injectors, 70 mm throttle body, 255 lph fuel pump stock fuel lines, vortech v1 6-8 lbs of boost. Ok car ran great but needed a bit more top end pull intake was killing me. I just installed a new holley systemax intake along with 42 lb injectors and new pro m 75mm mass air calb. For 42's., put a jeg's oile seperator and installed it in the PVC line to help with oil blow by! Car won't idle surges constantly fuel pressure is at 40lbs with vacumm off. Tried to adjust idle screw but no good. All lines are connected and there's no leaks. Any ideas.... Thanks
