Im driving my L on the freeway, I go to excelerate slightly and it starts to spit and sputter and slow down.

Now the only thing it will do is, idol ruff and when I give it gas it sounds like it's going to die.

The whole in-take looks fine and the mass air is plugged in.

I dont have any more ideas right now besides the fuel filter.

Any sugjestions.

 

What changed ?

Did you clean your K&N filter ? Change your plugs ?

Bad coil pack......

Injectors are pretty good on these trucks, I would doubt that it would be clogged or bad.

 

Change your fuel filter and try again.

Also - does happen from a stop and rolling into WOT or only at rolling speeds?

Fuel pump.

My low speed fuel pump developed a crack and caused the EXACT same issue... 2001 L

Go have it checked. Mine was covered.

 

Check your #3 (I think it is or #6) fuse under the hood.

 

Well the Mo Fo is getting flat bedded to the local dealer.

I have not changed anything recent,

When I start it is sounds like it's running on 5 cyl.
Then when I give it gas it just spits and sounds like it's gonna die.

?Whats the #3 or #6 fuse?

 

I believe these fuses are under the hood an corrospond to the fuel pump relays?
