Start having this missfires and the light blinking code 15 does anybody know what's the problem and how to get rid of it?

 

Code 15 is your ignitor. What motor is it? I finally got ried of my code 15 so if you gave more info like what type of wires your using (since you said misfire), how old is the cap/rotar (back to the misfire) the motor and what not then we could help you more.

Also is there anything else its doing other then misfiring?

 

the car is '89 honda civic si but the engine only is from '89 del sol everything else is from si
i have new rotor cap new wires new spark plugs and new destribudor and i still have the problem with missfires and my rpms after 4000 starting to go up and down even the car dies sometimes
