I just picked up a 2004 Rumble Bee, I understand that the plugs fire on different cylinders. I know there is a way to move the wires around so they will fire on the same cylinder as they should, I have done this in the past but have no clue what wire goes where anymore. Help.... Thanks.

 

What? Why? Lol

 

So both plugs per cylinder fire at the same time, never heard of this?

 

Aircraft do that....... but, adding that third dimension makes reliable ignition rather important.

I think the newer trucks also fire both plugs at the same time? The 'wasted spark' thing is all about emissions. How effective it actually is, is open for debate.....

 

Looking for the diagram so I can do this.

 

I'd like to see any evidence that this will do anything for you, the engine was designed around the dead hole plug firing, engines ran a single plug for decades. Are you tuned? I could see O2 sensor faults caused from the non firing exhaust stroke that supposed to burn up unused fuel.

I don't recall when/if this ever switched, 06+ motors quit running one plug wire over to another cylinder, but if they still fire on dead stroke I cant be certain

I don't understand what you need a diagram for. If you intend to follow through with this, just take the plug boot from the off cylinder and plug it into the cylinder next to the coil it came from?

 

Ya I figured it out, did this in the past on another truck. Thanks. I plan on tuning soon.
