Hi, JC.
I'm glad to hear you got a scanner that has CAN capabilities. You will be happy you got it.
As far as the codes, we have an intake runner problem. P2004 indicates it's stuck open. That could be the result of the backfire. The P2017 is a voltage issue for the runner which is likely being caused by a stuck runner.
Now, if the runner is stuck or damaged, you will need to replace the intake manifold.
I don't think that is what caused the backfire, but we need to check what is going on with it.
Here is what I'm suggesting. The diagnostics are somewhat extensive, so I am going to start with the P2004 issue. If I send everything to you, chances are you'll throw your computer at me. LOL Let me know if that sounds like a good plan to you.
I attached the diagnostics below. Let me know what you find. Let's look at one thing at a time.
Let me know what you find.
Take care,
Joe
