i have an 04 6.0 no programmer aem intake banks high ram and exhaust rough starts unless plugged in you can hear the turbo surge at idle and kinda slap like a 7.3 goin down the road. it shakes like torque converter unless your really into it then no shake at all deffinate power loss though and horrible fuel mileage new torque coverter so i know thats not causing the stutter what could it be?

 

That "surge" you hear at idle, may be normal, but hard to tell from here. Ford updated most of the 6.0's with a new strategy that actually cycles the vanes on the turbo at idle, to prevent them from sticking. I know my truck has it. It's odd though, my buddy has it too and his is way more noticeable than mine as far as hearing it, but both are the same year truck.

As for the shaking driving down the road, that's sticking injectors, not terribly uncommon. Does it go away once the truck is up to full operating temp?

You should definitely have your batteries load tested, and then test your FICM. There is a "how-to" at the top of the 6.0 page to test the FICM brother. Me thinks that's part of your issues right there.

Welcome to DB

 

thanks for the welcome! na the shake doesnt go away unless im into it anything below 2k rpm it shakes the surge wasnt there when i first got itit started when the shake did i want to say it seems like a misfire kinda. kinda got me worried stuffs a little pricey haha that truck of yours looks awesome by the way mines the harley edition i got 5 inch chrome mitres but them blacks like mean! ill def. try to test the batterys and the FICM tonight thanks for the info

 

Yeah test the FICM for sure man... sounds like it's all related for sure.

Thanks for the kind words on the truck. Get some pictures of yours up when you can!

 

tested FCIM everything looks good there right around 47.8

 

Ever had the EGR valve out and cleaned it? Might be a good time...

What condition are your batteries in? Have them load tested if you're not sure.

 

threw codes today all injector circ. are low 1-8 except 7 threw a contribution/balance fault and one more code fuel injec cont mod perf? whats this mean?

 

FICM is bad. Read the FICM test procedure at the top of the 6.0 page, test it to verify it is bad and then let us know what you find. The write up at the top of the page explains everything bud.

Once we get the FICM squared away, we can diagnose for injectors after, but chances are most if not all of those codes will disappear with a good FICM.
