Ok, so on decel my rpms surge, they will jump about 400 rpms and drop to normal. 128k miles, and it just started doing it. I noticed that my AFR's will hang around 15-16 when this happens. Since Decel fuel shut off is active, it should be zero (lines). When it is zero, it decel's as it should. It happens a few times a day, sometimes worse than others. Anyone else have this issue? I was / am leaning on a leaky injector.
