When im driving on the highway doing 55ish the truck will sputter and spit and when u push the gas pedal and it does not change the speed

Take it to a repair shop

No one can guess at all the possible
problems it may have

Unless you work on your own vehicles &
provide test results & have a specific questions,
we can't do much for you

look at fuel filter first

The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

i have the same problem.any help??

Clean your MAF (mass air flow sensor).

Google a Youtube video on how to do it.

You just need electrical parts cleaner or MAF cleaner.

You might check your fuel filter and hoses..could also might need carberator adjustment?

sounds like you have a vacum hose is off,

what codes do you have on it?

Internal combustion engines requires 3 things... fuel, air, and spark. You do not have enough of one or more of these. If the wires and plugs are old, change them.  Air filter, same thing.  Fuel filter can also clog up with stuff after awhile. When you take a look at the air filter check where the air comes from.  It is possible a little critter has built a home and blocked the air flow (rare, but, it has happened).

check your spark plug wires.
