6.0 missing badly

[StrokinKY]

Hey guys I have a 06 6.0 and it has been missing until it warms up. I recently had 8 new injectors put in it and a new ficm. I changed my oil and fuel filters yesterday now it does it all the time unless I have it to the floor. I checked my FICM voltage and its good...any ideas?

check your codes. mines sounds like its missing but it was the pedal sensor so i had to get a new pedal

okay so I changed my ICP and it still does it but not as consistently. Any suggestions??

More info is required. It sounds like stiction, but I doubt that's the case if you have new injectors.

Did you replace ICP plug harness as well?

One thing I've learned through the ownership of a 6.0 is to never assume anything...I had remaned injectors and 2 of them were bad. So I wouldn't rule out stiction.

Yeah never assume since they are "new" that they can't come defective. With the shop and working at ford dealers for the past 6+years, man made parts come defective all the time. My recommendation get someone either with an Ids that can see power balance at cold start and you'll find the evil injector, are you in the Houston area?

x2 to the injectors. Not saying it's that but I've seen alot of crap injectors before. If they came from Ebay or were super cheap that's probably what they are, CHEAP! But you should verify that you have good ICP pressure and fuel pressure before you condemn them. Low fuel pressure will cause a low power/miss also.
