While driving between or around 35-45 mph..if i give it a little gas to speed up..my truck shakes or sputters i guess you could say...hard to describe...but it idles fine..nothing has come up on the dash...all the fluids are perfect..shifts fine other than that..its only when i give it a little gas..if i hit it hard its fine and acts fine..i dont understand what the problem could be..i was thinking maybe bad gas but thats just a guess..Anyone ever have this problem or know what it possibly could be? Any help on this would be great...Thanks - Matt

 

First guess Sparkplugs or a COP.
Second guess, Fuel filter!
Third guess, voltage on the TPS.

What are your mods???

 

mods are flowmasters and airaid intake

 

sparkplugs or coilpack,pull your plugs

 

+1 on the plugs and coils.
Could possibly be a Torque Converter.

 

So, you are basically stock…

I had a coil problem when the truck was about (1) year old, at idle and with a slight acceleration it would not be smooth, stumble and a very slight miss.

Took it to the dealer, I had the guaranty at the time, and they replaced two coil packs that fix it…
