Well the problem started after i replace my p28 for my b16a with a jdm p30 for the first couple days everything was fine. Now the car stutters a bit like it dosent wanna go. The cap, rotor and button have been replaced also the spark plugs and wires to. Also when i went to replace my rotor the old rotor screw was completey gone and the rotor was just barely on and had chewed up the black plastic piece inside i dont know if that helps

 

replace that rotor and get a new screw. make sure that it didn't burn anything like the cap. I'm not sure if this happened before or after the replacement of your ignition components. Also make sure you have good grounds.
