truck runs bad when hot
 

hello my truck is great and runs fine when it is cold and has lots of power all the time but when the truck warms up the truck get very sluggish and loses power like crzy. if i try to floor it it will sometimes pick up sometimes wont and wont get up hills very good but when cold it will no problem.


any help is thanked:icon_angel:

update now the truck just runs kinda bad no matter the temp. i have replaced the fpr and fuel pump(which was shot) a month ago but it just doesnt want to get up and go. especially up hill.
