Truck help | Slightly sputters when accelerating
Posted on 7/29/20 at 8:25 pm

Doesn’t do it often but I can definitely notice.
Also at times, there’s a slight pause when I floor it and it begins to accelerate.
Fuel injectors clogged?
Change fuel filter?
Can I do either myself?

Maybe quality of gas? My Acura is very finicky regarding gas. My wife put in regular once and it sputtered the entire tank.

F150? After the transmission recall fix, it feels like it is often in one gear too tall.

Spark plugs maybe

When was the last time you changed your air filter?

If it has coils on each cylinder, a bad one of those could do it. Easy to replace.

Sounds like spark plugs

If you have any overdue filter changes, do those. If that doesn't fix it bring it in. It'll end up being cheaper than throwing parts at it.

Is this a gas burner? GM that switches from V8 to V4 when you’re crushing? My Silverado does this and it’s annoying as hell. Hit the gas and nothing happens. It’s like the truck is thinking about it

Start with this.
Depending on year you will not have an inline fuel filter.
Is the Check engine light flashing or on?
What year truck we talking?

Recently purchased a range afm disabler to take care of this issue on my Chevrolet and so far its working out nicely.

Depending on year his truck may not have AFM or DOD.
I wouldn't say the feeling you get from AFM or DOD swapping from/to v4-v8 is a sputter either. Sometimes you will feel it slightly as it flops, but surely not a continuous "sputtering" feeling.
My new truck has it; still am undecided if I want to disable it when I have it tuned.

2014.
The check engine light has come on twice flashing, but only lasted about a minute and went off both times.

Considering it has flashed and you're noticing a "sputter" it will be a misfire issue.
Have the DTC codes pulled; you should have a "random cylinder misfire" or "a specific cylinder misfire".
If the ECM can not detect or figure out which cylinder it is; you will get "random".
You either have a fuel or spark issue and most of the time its a spark issue.
I would begin by replacing all spark plugs.
Test the plug wires (if you can)....if not, replace them as well.
Pull DTC codes, if you're given a specific cylinder misfire....
-Swap that particular cylinder's coil pack with a different cylinder's and note which you moved it too.
-If it happens again, pull codes again, if the truck gives a misfire for the cylinder you moved the questionable coil pack too; it's bad and needs replacing.
GM to my knowledge quit putting inline/serviceable fuel filters on their gas trucks in 2002.
The only easy thing to test would be to test the fuel pressure on the fuel rail.
ETA-
2014 would make the truck 6 years old.
I would imagine the truck is at or over 100,000 miles; if you haven't changed the plugs/wires yet.....It's most deff time to change them anyway.
