How to check the coil packs on my 2000 2.7L 3RZFE engine?

I would like to check them. My truck bucks while driving and has been doing so for a long time. Plus my mpg sucks. I have always been regular with maintence. I replaced my MAF sensor. I replaced my whole damn head with a new one because the dealer told me I had burnt valves which wasnt true. So I would like to check my coil packs. How do I do this? Thank you.

Here's the trouble shooting diagram for the ignition system. Are you throwing a code?

You could just need a good tune up. Change plugs, clean throttlebody, and a good seafoam cleaning.

My check engine light use to come on all the time but now it doesnt. Every once in a while it does but then it goes back off.

I checked my coil packs and they are all firing. I dont know how good the spark is but all the sparks looks about the same.
