Well I finally got my car back together running , The car seems to have a dead miss no power, It seems the idle is smooth, tach is not jumping or anything, I also pulled the head to replace the gasket I also replaced passenger side plugs, I have checked for crossed plug wires, Vacuum leaks , Injector order all seems to check out , only thing else I can think of Is maybe i cracked a sparkplug on the install? or Maybe something wrong with the Injectors, I noticed Little white Square O rings from who knows where, After I pulled the fuel rails, Does anyone know what these are ? Can anyone help There was no miss prior to the Install
