Injectors or ?

[LvGolfer962]

I cant recall if this issue was there before i bought it, but when the truck is in gear with my foot on the brake its a little rough(shakes a bit/rough idle) and when the tq converter locks up in high gear it will buck/chug/sounds like a miss if you try to accelerate. Oh, and it feels a little sluggish when taking off from a dead stop

Ive recently done the bullet proof egr cooler, oil cooler, t-stat, blue fuel spring, oil, every filter change, trans fluid, belt, coolant and hoses. No check engine light and i threw my sct from my other truck on there and it had no soft codes either

From what ive read it appears to be some bad injectors but my im thinking it would have these symptoms in every gear through the rpm's

so anywhere else i should be looking before i take it to the stealership

have you checked ficm voltage yet?

[LvGolfer962]

I have not. After all my reading i kinda skipped the ficm because everyone said they had starting problems and smoke. Mine starts right up and i just had a smog test and my particulate/smoke reading was zero. Not that it means its not bad but the ficm has been replaced once before.

I need 48 volts with the key on and 45 or more when its running?

Another thing i noticed was when i pulled the batteries out they were from 07. I know from experience that my 03 f150 will do some weird things when the battery get weak, do the super-dutys have similar problems?

yes .

Ordered a swamps 58v ficm since the previous owner was wrong about the ficm being replaced, it was the ficm wiring that got fixed on a tsb. Anyway the swamps ficm arrived this morning so i got right to it.

Once I had removed the old one I was checking things and pulled on the injector plugs to make sure they were all locked in, found one that was loose. So im fairly sure that was my problem the whole time but im glad i went with the swamps unit anyway. As soon as you turn the key the glow plug light goes out and she starts right up and purrs, and the extra power is nice too

The injector plugs should be locked in with a clip. Was that missing?

The clip was on but the plug wasn't seated, so it didn't get locked down.

Im just glad its back up and running right again
