So I picked up a wonky stumble in OD on the interstate- light to mid throttle, 55-75 mph or so. It was like you dropped the throttle for a split second and then it picked right back up.

I swapped the APPS and it fixed it for a month or 2, and it started again tonight.
I'm gonna reset the apps and see if that has any effect.

Anybody had this happen?
Thanks in advance.

does it matter what you are running tuning wise? i know when I had a comp box, with agreesive but not full throttle accelerating on the interstate it would shudder a bit.... but on stock it never did it...
 
It is almost like I drop the throttle and jump back on in the exact same spot....
I'm gonna pull the fuse on the fuel box to see if it changes anything.

yeah could be a poor wire tap.... or the damn pump, we all know your truck doesn't like vp's....
 
That'll make it stumble in every gear :D

The 24v I'm driving now does that occasionally but its bone fuggin stock.
 
You might drop 30 bucks on Speed sensor if it only happens on the highest at that speed
 
I've had a stock pickup do that due to a bad MAP sensor. It was still in range, so the ECM didn't pick up on it. But driving around with a scan tool you could catch it reading low- de-fueling the pump.
 
I reset the APPS and it cleared up. The old girl just likes to keep me on my toes I suppose.

I get this on mine if I leave my box turned up. Which I don't drive it much and I pretty well just leave it on 6 and drive with an easy touch. I like the throttle response of the higher levels... Guess I just have to deal with it.
