Here are the instructions as requested and I have included a misfire guide that might help as well:

Here are how the fuel injectors are replaced, it looks like there are special tools involved to check the fuel injectors out. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Its most likely the injector. I will replace the plug as well. Ya there is a tool for everything now but i managed to get the injectors and rail out, i lost my spark plug 12 pointer tool for this plug so I ordered another one. Will see how it goes.

Sounds good, let me know please.
