问:粗糙的闲置,p0300代码,运行丰富

最近重建的引擎,安装了一个更大的凸轮轴。功率计调好,跑600英里引擎,现在勉强运行。开始停滞不前的时候我我让加速器后30英里。低权力但运行时,摊位加速器的释放,粗糙的闲置。加器传感器取代,长期燃料阀内件是-5%到-20%。失败数很高缸# 6。检查插头,不是犯规。将线圈没有变化。把喷油器rails,没有泄漏运行的关键。O2传感器似乎工作。 Evap purge solenoid not leaking. Fuel trims respond when vacuum leak is introduced to system, so it's running rich. Any ideas? Failing MAP sensor? High fuel pressure from faulty pressure regulator? EGR system is deleted, catalytic converter is deleted, AFM deleted mechanically and electrically. Any idea what the problem might be?
