charcol canister.

pcv valve was just done and already checked that.

I do alot of offroading but then bring the truck home and replace/inspect everything.

it just did it today. no sign of going just appeared.lol.

I was thinking somthing in the upper intakes but i did them in the summer when the truck slipped into a 5 foot puddle…

I planned on changing the fuel filter,plugs and also cap and rotor.

But i just want to make sure its not something else and will have to replace everything again in a day or 2.

Thats the other thing how do you know when the injectors are shitting the bed? i dont know if its the same as the old tbi units.

Also you think it can be something internal in the motor like a ring or something in that nature?

Also i would like to thank everyone for there response. And keeping this thread clean and no bullpoopy.
