Just want to know what I need to buy to clean out my plugs?
Apparently plug #4 is giving me heavy deposits which is causing my engine to shake at idle.
Any help or suggestions

 

Another input,
Is having your engine shaking(when idling) and high idles the same thing or different?

I ask because I have both problems and I am trying to have one solution

 

brake cleaner and a wire brush

 

Are we talking about spark plugs, or injectors? If they're spark plugs, just replace them - one spark plug costs $2, a can of brake cleaner costs $4. You do the math. If you're talking about injectors, have them done professionally.

 

x2, this.

 

What color are you plugs can you post a picture of them.....might indicate a condition within the cylinder.
