Message: [QUOTE="The Brad, post: 1265675, member: 14154"] MFD is Mass Fuel Desired measured as mg/stroke. When you cancel an injector, the others need more fuel to maintain desired rpm. The best way to cancel an injecitor is to use a breakout box $$$. The cheapest way is to unplug them one at a time under the valve cover. I've been meaning to update this for awhile, but I haven't amassed enough data yet. I bought a commuter car, so the truck sits. Anyway, I added some Hot Shots to my last oil change and instantly, the idle was perfect for a 100 miles or so. Then, it started surging every now and then at idle. While surging, the only change is in MFD and Inj PW. So apparently, my injectors had stiction issues. [/QUOTE]
