Testing fuel injector harness...
I still have too much fuel getting into one cylinder. The plug is flaky, sooty, and black. The electrode is chipped too.
I have rebuilt the heads and it's not oil. It is definitely fuel and I know I'm running rich to boot. It's not a leaky injector, unless they all leak, because I have swapped them several times. So, I'm left with the possibility of a malfunctioning electrical harness, or an O2 sensor problem, or both. I am going to torch-clean the O2's and check the readings with a meter as they heat up. I have no idea how to test an injector harness. Any ideas?
