Been a bit since I posted on here, but I recently swapped sticks to Full Force reman stage 1 (180/stock) single shots and am running a php hydra with tunes from FFD for single shots. I have drove 70 something miles after the install. I am having a rough idle...kind of chugging...like its not running on 8 cylinders. I jnplugged each injector one at a time and each one made it run rougher. I did have a buzz test done and a contribution test done. Buzz test was good but cont. test showed #5 fail. However, as stated previously, it made the engine run rougher when unplugged, so it seems that the #5 injector is working. Here's another thing. I went cheap on gaskets and bought Dormans. I swapped them back out to my old Motorcraft ones and no change. Could this be a tune thing?? The truck runs good driving down the road, but idles terrible. Sounds like a gasser with a big cam in it. I wiped the Hydra clean and only programmed a 65 hp Daily Driver tune on it to simplify things. Anyone have any experience with this kind of problem? I dont have AE or anything to look at ICP or IPR bur I unplugged the ICP to see if it smoothed out but it didnt.
