Truck started running rough then would die. It sounded like it would choke itself out. Replaced fuel filters and ran fine foe about 25 miles then started doing it again. Truck runs good down the highway but won't idle in gear and lopes when in park.

[sbfd1268]

Notice any chug chug chug sound when it was "choking out"? Thats the sign of a failing/failed injector(s) thats sticking open. Does it smoke? If its blue/grey and thick be concerned.

Truck does not smoke at all

It seems to only do it when it's warmed up

only when warm-ficm seems to be the culprit.
