New f150 owner (first time truck owner) Got CEL code P0201 :(
Hi everyone,
This is my first truck ever. I knew it had some acceleration issues (hiccup, jerky, fluttering) which I thought was caused by condensation in the cac. Drilled the hole, barely any liquid came out. I have a p0201 error using my diablosport tuner i2.
So at this point I'm ruling out any issues with the cac, which now I want to plug up somehow. Any ideas on that?
But as far as the p0201 error, it leads me to believe it's something with the injector. I couldn't find anyone on this forum with this error code, mostly the p0301 codes which is due to bad spark plug, and not injector.
Any insight would be appreciated as I am now unsure if I made a good purchase lol..

What is the year and mileage of the truck? Have you changed the plugs recently? You don't need to plug up the CAC. There are no residual issues with having the hole.
I would start by resetting the code and removing that tuner from the truck. Run it for awhile and see if the code comes back. Diablosport has had issues on these trucks previously, though I'm not sure about that exact code other than it being a Cylinder 1 injector issue.

Understood about the cac, but rather not have a hole leaking fluids etc unless needed. I thought about screwing a little screw in there but we shall see.
As far as I know, this car has never had plugs replaced, but for plugs, I thought it was usually a p30-- number not p201 which is for injectors specifically.
The code has been reset, and diablosport back to stock tune, BUT, I still have the studdering issue, even though CEL is now off.

If plugs have never been replaced at 115k miles, then I'm surprised it runs very well at all. These trucks need plugs replaced every 20-30k miles to ensure they are working as best as they can. Turbo engines are HARD on spark plugs so they require them to be replaced much more often. I would be the gaps are either way blown out past what they should be and/or you have varying gaps across all of the plugs. Change the plugs and start there with the stock tune.

Yup that was the first step I was going to take. Any specific brand you'd recommend? I'm seeing different opinions on that all over.

Just use the factory Motorcraft SP-534. They are already gapped .030-.032 (check to be sure). They work the best and perform great on stock or tuned trucks.
