Several symptoms, need help

2003 f350 6.0. Only mod is coolant filter. Here is what is going on: feels like a miss at idle (not all the time, sometimes rougher then others), rpm not fluctuating. Can feel it some times while crusing down the road (all speeds). Taking off from a stop will get black/grey smoke until it shifts up, also small amount if I get on it. No engine codes showing up when scanned. I am running fresh syn oil, new filters all around (ford filters). I am thinking possible ebp sensor. Any suggestions?

Could be EBP...or low fuel pressure. Have you checked your fuel pressure to make sure your not starving the engine?

Dont have a way to check it. A fuel pressure gauge is next on my list of mods. This issue has been going on for a year or so. It is just recently getting to the point where I am going to get it resolved. I did a search and came up with the ebp sensor as a probable cause but it could be something else aswell.

Could be EGR valve too, or any number of things. Should really get it scanned for codes before you start throwing parts at it.

your 2003 more than likely doesnt use EBP it uses MAP

At KOEO check BARO,MAP, and EBP if you get it

what about the EGR valve do you still have one have you cleaned it???

How do you check the BARO, MAP, and EBP.

The egr valve is still in. I cleaned it about 4 months ago. It is the updated one with the pink dot. Everything there looked good. Just normal carbon build up. Nothing wet or stuck open.

Update - resolution: I took the truck in to have it looked at by the dealer. Had two injectors going out. Had them replaced and it is back to normal. Smoke is gone on acceleration, miss/stumble is gone. MPG is back up and all my power is back. Wanted to post so those who see these symptoms will have something to look at.
