So I'm sitting at a stop light, no big deal. Light turns green and I press the go pedal.

Truck dies for 1/4 of a second and then comes back like nothing happened.

Sound like a CPS?
I don't have a spare right now. Don't even know which I have in right now. But I'll bet I have the recall replacement.

 

Throttle pedal assy would be my guess. Probably the IVS is sticking.

 

I believe that for 02-03 it had lawsuit on it.

Is it rain in your area when it died? It could be cps.

Mine would running but cut off on highway it pause for 3-4 then run again. It does that during rain.

 

Could also be impending IDM failure. Mine did that shortly before dying completely. I would get home or to a shop.

 

It's not raining right now. Also, when it happened I think my tach died. But it was fast and wasn't looking right at it so im not sure

 

Thinking about it more it could be an ICP or IPR issue more than the throttle pedal. Earlier I missed the fact that it stumbled too. Have you checked the ICP sensor for oil on the connector?

 

Nope. Should I? haha
