Close. Both plugs in each cylinder fire at the same time, not each bank of plugs. On the power stroke, two plugs fire, and on the exhaust stroke the plugs fire again with much less voltage. This is called "waste spark," and basically is just a ground for the secondary system due to the low resistance in the circuit.There are may functions of this system most of which are for emissions purposes. One interesting function is that one bank fires on the combustion stroke, the other on the exhaust stroke if I am not mistaken...
That would be the fastest piston engine in a ground vehicle...in the world.In the late '80s top fuel dragsters started using dual plugs. Just think, Your Ranger has something in common with the fastest internal combustion engine in the world!!!
They still use two plugs/cyl on the top fuel/funny cars. it is in the new Hot Rod mag I got last week.In the late '80s top fuel dragsters started using dual plugs. Just think, Your Ranger has something in common with the fastest internal combustion engine in the world!!!
Just go to Autozone. If your check engine light is on and/or your engine is throwing codes then they'll scan and tell you the codes for free.Thanks for all the posts. I havnt been able to work on the problem yet but will let you know how it turns out. But can anyone tell me how to pull the codes on this thing?
