My 07 Ridgeline developed a hesitancy from stop to acceleration around 100k miles. Honda service did "snapshots" and all electrical components tested ideal. I went ahead and replaced spark plugs and changed transmission fluid through Honda. From dead stop with normal acceleration there is a pronounced hesitation so that I have to push through the "dead zone" to continue accelerating. Afterward, the surge occurs at all speeds but is most noticeable at lower speeds. When the RPMs are up, it is less noticeable. From here it shifts down hard from D on most declines and continues to be hesitant to pick back up on the throttle. The surge feels like it is holding back. Otherwise, the engine runs like a quiet, smooth sowing machine, especially in idle. I oiled the original accelerator cable to no avail and then replaced it with a new factory cable, also to no avail. Any ideas?
