F150 misses code 0302

How do I get the fuel injectors out. Is this a easy thing to do? I got a code 0302.Replace the fuel filter now going to try the injectors.What next can I do.

The missing comes and goes.

Here are the instructions: http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c152800af8a7 Save some money by swapping #2 fuel injector with another. Drive the truck to set the code. Read the code. If the code moved to the other cylinder, then the problem was in #2 fuel injector.
If the misfire code stays P0302, you’ll need to do some troubleshooting.

I have a 1997 F-150 with the 4.6L v8. When I had codes that indicated an engine miss I ended up replacing the coil packs. I replaced one side and then within a couple of weeks started getting a miss on the other side. That seems to have resolved the P030x codes for me.

Forget what I said. Just saw your first post where you already did this.
