Does it blink all the time or just a little once you first start the truck?

What year is the truck?

If its OBD II, 96+, then you can swing by an auto parts store to get your codes run. Then post the codes here and we'll give you answers.

It only brinks for a minute once the truck is warmed up. It's a 2k and I had it checked before and I got p0174 but that was with no blinking

It could be a bad o2 sensor.

So the light doesn't stay on, it literally blinks like a blinker?

Probably an o2 sensor, maybe the rear.

Thats for sure a bad o2 sensor. Probably the one closer to the motor, not the one after the cat.
