new injector or injectors in my future.

Well before I start I'm on my second round of REVx and that has fixed alot of issues and my FICM volts is 49. anyways the last two days the temp outside in the am has been 25-29*F and this is what I get for about 10 mins. this is at it's worst because it tapers on and then off. it smells like raw diesel..... I'm at work and still stink.

no codes, but the truck does feel like it's missing on one or two cylinders. I had it to the dealer before using Revx and they didn't find anything. Since using the revx the problem is more noticeable and my guess is that the other injectors are working better.

Get the dealer to check for codes, and run some diagnosis on the injectors, if that's the type of codes that come up. The FICM voltage you mentioned, is that KOEC, or KOEO?

I check for codes and also the dealer and nothing. last time I had it in they did a power balance test and found nothing but they did not run a contribution test on it. The FICM is fine I just had a new half shell installed a couple months back and it never goes below 48v at and time or test...... the miss get worse the hotter the tune I install which is why I going to have the dealer test it tuned and not tune while I'm there. the problem seems similar to this post here : injector issue BTW that thread is a good read for anybody

Bad Injector-- Overfueling. You can isolate which injector it is by unplugging them one at a time, when the smoke goes away you know its that cylinder.

So, you only have issues when the truck has a tune installed? How does it do when it's stock?

In the above photo that is stock tuning, it will do it also while tuned. Now what seems to be a cylinder or cylinders miss is more noticable when tuned. it is not a programing issue, it is a injector issue. the bone head at the ford garage doesn't seem to think anything is wrong... that is why I'm going to go back and have him test it while tuned.

Yeah, the tuning usually amplifies problems like yours. Hopefully he will find something this time. That link you posted was pretty interesting. Makes me wonder if he was using a cheaper fuel filter, like Fram, or something other than Racor or MC
