having a issue

hey everyone love the forum. i have been lurking around for quite some time now. so i am having a problem with my 97 f350. when i start it i have to let it idle for about 15-20 when the temp gauge starts to register before i can go anywhere. if i dont wait and decide to take off it will not rev past 1k rpm and have to floor the pedal or else it will just die. i have looked around and cant find any info about this issue. any info will help. thanks

May have a weak thermostat. Mine takes about 10 mins of idling to start to register.
The loss of power is your EBPV. There is a sticky about it in the 7.3 section.
Winter Operation, Hard Starting, Hissing Sound Etc...
Nothing much to worry about.

It closes depending on parameters that the PCM receives like EOT and other stuff. It may be incorrectly operating cause they can mess up. You can unplug it from the base of the pedestal and if it doesn't do it anymore, that was it.

Ok well what about maintenance? Fuel filter, oil and filter?
Your fuel pump could be going out or the FPR screen could be clogged. Should check pressure.
Your UVCHs may be worn out, they should be checked too.

You might wanna do oil changes a little more often. 7.5k at the most is what i do. around 5k is better because of how hard the HEUI system is on oil
Pressure should ideally be around 60-65 but you wanna see minimum 50-55 I'd say. Check it idling and under WOT.
Do some searches for those two. There's a ton of threads about them. Someone just made a writeup on the FPR screen.
