2008 6.4 with H&S tuner. Truck runs perfectly fine, always has. Dont notice any other issues. But has been throwing a check engine light the past couple weeks every couple times I start the truck.
I tried returning back to stock and then re-loading H&S and the check engine light came back after 4 or 5 starts.
There are no other codes present, and the truck still drives perfect.
I read about TCMs but dont know if my problem is specific to that or not.
I can continue to clear the check engine light whenever it comes on, but I would like to know the cause of the problem and if there is a repair/replace for it.
Thanks
