OK, I have a long(er) than normal start problem, that is oftentimes associated with a "kickback" during a cold start. It started this about 4k miles ago... I have since driven to New Mexico.
I am fearing an injector, but tell me what you think:
Rail pressure is normal... 6k psi idle, 16k cruising 65mph, upwards of 26k-ish WOT. FCA was replaced around 100k and the rail bleed valve was tested at the same time.
Oil smells sweet, but not like fuel... I use Rotella... it feels good between the fingers, doesn't appear diluted any with fuel. The oil level has not moved (if anything, its down), but the oil itself is black (but it should be with almost 10k on 1. 5 gallons of it and 20k on the other 3 gallons). My UOA 10k ago indicated no fuel... I'm in the process of getting bottles to send a new sample into Blackstone (I'm on the road)...
Truck idles eerily smooth and quiet around 750RPM IIRC (maybe the altitude?). There are no odd noises, other than the typical 140k mile 3rd gen noises.
I'm blowing tons of black smoke if I try... but that is really no indication since I am in New Mexico at around 7k feet (its more/less typical for this truck at this altitude) but I feel it might be "excessive" for a completely stock truck. Once it gains RPM and boost, the smoke goes away... but I can easily smoke the guy behind me by just rolling into the throttle slightly. The company has a 2007 2500CTD 5. 9L auto (completely stock) and it makes zero smoke on the same terrain (auto versus manual??)
Fuel mileage is surprisingly good... I average 20mpg for the majority of this trip... the last tank was 18mpg, but I fought a head wind for most of that tank.
And the truck has had all the current flashes done up to 2005... white smoke and mileage.
Any ideas??? Anything else I could easily check in a parking lot?
How hard are injectors to replace? Is this a major undertaking, or an afternoon's worth of work? (I have all my tools with me)
