How do you change the 3 rear spark plugs on a 1996 3.3 Dodge Caravan?

It's not normal to be able to hear the sparking in the cylinders because the small noise the sparks make should be drowned out by the explosion of the fuel and moving parts in the engine. What you are hearing COULD be arcing electricity from the coils or wires, but I'd be surprised if such a new car would need wires already. However, since you are troubleshooting hesitation, it's something you should look for.

With the engine OFF (we don't want you getting hit by an errant spark!), remove the engine cover and whatever else you need to remove to get a good look at the coils and wires. Start the car and see if you can find the source of the arcing. If you can see it (it might be easier to see at night), you definitely need to replace the coils and wires.

It's cheap and easy to do yourself. If you aren't convinced that it's a spark plug wire, ticking noises can also be the valves. One solution to this is to use thicker oil, which will help hydraulic lifters that rely on oil pressure.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
