[QUOTE="Charles, post: 1339286, member: 103"] Glow plugs have no bearing on my point. No smoke was coming out the pipe, therefore no fuel was being injected, regardless of whether or not the cylinder was warm enough to ignite it. And my glowplug system is 100%. New motorcraft plugs went in with injectors. The point of my post was to point out how much time it takes to actually get the rotella to move into, and shove down on the intensifier piston when it's super cold. Out of those 8.6ms, only about 2.5 of them were actually injecting fuel! Yes. This program comes back to idle well. Seems to be an issue with not having a good balance of ICP and MFD near and below idle speed. The PCM will stab the MFD up real hard, then bounce up, down, up, down, up, down until it settles out. A way to adjust the actual correction speed would be nice. But getting the values it has access to under control cuts off its ability to romp around too much. Worst case I will get a single WACK, when it comes back to idle right as the converter unlocks or something. But usually nothing. Just hits idle. [/QUOTE]
