Check out this 10 second data log. The
Peak to trough AFR is ~13 to 9.3. I think this may be the bottom of the scale for BS3's sensor. I checked all but plugs 7 & 8, and so far they looked good. I tried idling it in the driveway and pulling each injector's connector 1 at a time. It didn't make an immediate difference, but then it may be so saturated in fuel it'll take a bit to burn it off. I dunno.
If it were a fouled plug, I would expect to see that cylinder read lean, not rich. My only guess is an open injector. I honestly had no idea until I connected the computer for the first time in a while that this was even happening. At low engine speed, I could feel what felt like a miss, but it wasn't consistent, and I just figured that the engine didn't like load at low rpm.
Do you have any ideas?
