To fellow modlers,

My expereince with small engines and automotive is eleven years total. All standard plug wires leak KV [ killavolts]. that is what interfering with your recievers, pcm recievers is just a bandaid, If you notice on the higher end engines such as DA and 3W, there wires have shealed wires, Some one in here said twisting servo wires does not work, thats false! When you have 2 wires in parralle, they leak a frequency or voltage as such and can cause havoc on recivers and servos, servo wires are not sheilded, if they were they would be much more expensive, In some cars I have worked on they have had bullentens on noise intereference and most crank position sensors are sheilded because if they pick other noise they will run like crap. Im not no expert at anything butg have basic understanding. And like some people say in here metal to metal causes interference, True, some people over look the littlest things such as, metal arms on metal gears servos, loose spark plug connections, A single cylinder engine creates a lot of vibration which is turned into a frequency. Helpful hint use a hose clamp on the Bosch plug caps, it keeps it tight.
