Message	Making a new post as the other one is a few pages back now. Still having the issue and kinda at a stoping point with what I can do for free-ish. This issue wasnt what the car was brought to me for to have fixed, but its something I want to find and repair before letting it go back to the owner. But I do need to get it out of my shop as I have others waiting. Heres the original post: Stumble at low rpm, kinda stumped. Some more updates: I did change out one of the O2 sensors for the hell of it with a new one the owner had. No change and it reads exactly the same as the previous one. And both sides read/act the same as each other as well so I'm saying they are both good. They also both appear to have been replaced before anyway. And they are Nissan O2s from Courtesy Nissan. Battery and alt are good, owner had these checked. Not a power issue but someone had asked about these so I'm answering. All connections are good. I went through all of them while it was running. I would wiggle and mess with them to try and get a change but nothing. I'm still leaning towards a fuel or ignition issue since it feels like a miss. But as mentioned they are all firing/working. Also spark plugs are new (they are not fouled and look to be burning normal), coilpacks tested/swapped out. CAS swapped, PTU swapped, injectors ohmed good. Fuel pressure holding so doesnt appear to be a oring issue. Anyone have any other suggestions?
