Do you have MHD for logging? One way to check for leaky injector(s) is to cruise down the highway and completely lift off throttle for a few seconds. Within a couple seconds your AFR should hit a hard limit of 234.something - I can't remember the specific number, but it's a hard stop with no fluctuation. If it doesn't do that, an injector is leaking. The caveat, I'm not sure of the sensitivity of this test. If it's a super slow leak that must sit overnight to accumulate, I'm not sure if you'll necessarily be able to detect it this way.
