Possible bad injector
Hello all looking for some advice here!
I have a 05 F250 xlt 4x4 with 118500 miles all stock. Has been serviced regularly since i had it (2007) lately the fuel mileage has been less than when i bought it and it is very hard starting when cold. After it starts the engine runs a little rough and you have to really step on it to get it to rev clean. Once it warms up it is good. I have been told glowplugs but I live in Florida and it doesnt get very cold here. I was also told might have a bad injector. I am fairly good with mechanical skills and any work would be done by me because it is out of warranty. Any advice or web sites I can read up to help diagnose this will be appreciated as well as any hands on experience would love to hear it. Thanks in advance.

More likely to be a FICM or an injector than glow plugs.
The Tech Folder has a "how to" on checking your FICM voltage.
Is your charging system healthy (batteries and alternator)?
Can you get the codes read?
When was it last "reflashed"?
What oil are you using and what is your change interval?

not a glowplug concern in the middle of summer in FL. I can promise you that. use the search function and look for ficm testing. start there.
to diag an injector you will need some form of scan tool.

I have an OBDII scanner if that helps? Which one would I need. My alternator went out a few months back and truck was running made it home with it bucking and every electrical device was off. Battery was at 8 volts and hot as hell. I think it was reflashed a long time ago the E085 one I beleive might be wrong though. I use shell rotella t 15/40 and change right around 5000 but never more than the recommended 7500.
