2004 6.0 stalling
Okay so here are my symptoms
it Stalls on the road at low speed / low engine RPM.
Throttle pedal becomes completely unresponsive. Stabbing the throttle pedal repeatedly sometimes causes it to return to operation. Sometimes the engine must be shut off and re-started to return throttle pedal to operation.
Rough, surging, stumbling idle at rest.
Will crank but not fire occasionally. Problem has become worse as of late. Repeated attempts at starting the engine usually result in success after much, much retrying.
no codes are being thrown however the ford mechanic said the only thing out of the ordinary is that the ipr is at 23.4%
things that have been replaced
hpop
icp
ipr
intake manifold
turbo
engine and injector harness
entire fuel rail
batterys
alternator
cam and crank sensors
ficm
that is pretty much all i know ive had 3different mechanics look at it a 6.0 specialist, international, and ford non of which can tell me exactly what is wrong with my truck and i am tired of just throwing parts at it any help would be greatly appreciated
thank you,

The first thing the 6.0 gods here will prob tell you is to get some gauges to read real time data so you can see what's going on.
Afew options if you don't have any are scan gauge, edge cts, dash boss or torque used with the iPhone or android

Unfortunately to "just fix it" you will need some sort of monitor to see what exactly is going on. The dash gauges don't mean squat and as you've already experienced the throw good parts at it technique is a labor intensive/expensive road to go down. If your ipr is 24% at a hot idle then it is exactly where it should be (might be a good time to find another shop). Suddon stalling I would look for electrical issues more than anything (03 & 04's are known for chaffing harnesses). Does the truck just slowly die or is it like someone turned the key off...no gauges, light, etc

i would definitely lean towards an electrical issue then. if i recall (and maybe someone can help my tired memory) weren't the some people having troubles will the instrument cluster causing an electrical nightmare? rough running idle/stumble usually points to icp sensor and the pigtail, a hard hot start is usually a leak in the high pressure oil system/pump. but usually the truck doesn't just shut off. i guess a simple and free test you can try is unplugging the icp sensor when it is acting up and see if anything changes. hopefully one of the 6.0 guru's can help you along further

might be a video worth checking out...also shows why having a monitor of some sort is necessary in diagnosing these trucks.
its worth spending some time on his youtube channel...lots of great info!

Okay so all injectors are bad however just did an oil change and whoever did the oil change last time over filled the oil I would say there was probably around 18-19 quarts of oil in the truck is this going to be a problem?

I find it hard to believe that all 8 injectors are bad, how did you come to this conclusion? Was there any DTC's?
