After the truck started to run so bad and bunch of codes that Santa brought, we decided to go for a full tune up:
Coil packs
Spark Plugs
Spark Plugs wires
Clean the MAF sensor
and all gaskets needed for the job
I'm starting soon and will try to post pics as doing it.
So if someone sees a big NO NO, please jump in!

 

let the party begin!

 

Couple of questions when I read your post

1. Why not do the O2 sensors?
2. Why not buy a new MAF instead of cleaning it?
3. What about a air filter?

 

ac is out

 

nasty!

 

good grief!

 

wow..
they are going to need some serious cleaning

 

nasty leaks

 

driver's side out!

 

That is bad but the rockers look better than some others. I took all mine to the head shop and had them clean em in that ultrasonic bath they use and it got all of the carbon build up out of it. If you can do that, cover the ends with ziplock bags and duck tape and pour mineral solvent in them (I'm talking about the intakes removed from the truck) and that will get that carbon build up out of em. You can disassemble your throttle body real easily if need be or you can take just the butterfly out and clean it real well and then inside of it. Makes it a ton easier
