I've had cold running problems from sticking 6.0 injectors for a year or so. I tried all of the snake oil additives the aftermarket sells: Optilube, Rev-X, Hot Shot, Archoil and some German crap. Bupkis. Actually hundreds of dollars less than bupkis. So I sprang for factory injectors. $3800 worth. The good news is it runs perfectly, much better than before even when warmed up. Super smooth, excellent low-end and clearly more power. Bad news is someone else had to touch my van besides me. Courtesy of Courtesy Ford:
That's the oil filler tube that plugs into the right valve cover. The mechanic broke it and expected silicone to hold it in place. $11.09 is what the new part cost me, but at least it wasn't something that would destroy the engine by letting in tons of dirt. Wait, it is something that would destroy the engine. Luckily the intercooler hose popped off, again, so I noticed the filler tube was no longer connected either.
Earlier this year, in preparation for my new injectors, I added an Airdog II fuel pump and a regulated return system.
Once I realized I had to turn the fuel pressure regulator on the pump itself all the way up, the regulated return system maintains an excellent 70 psi, or close to it. I keep the regulator wrapped thoroughly with heat wrap to protect it (not shown). I also added a fuel pressure gauge to my Edge CTS2.
I now have plenty of gauges to obsess over. I also added an ambient temperature sensor, so, like in a modern car, I know how hot it is outside.
If you have sticking injectors, just replace them. They told me three of mine were bad, and I believe them.
