Wondering if anyone else has experienced anything similar to this.
Bank 1 AFR tends to be richer during transients. Cylinder 3 plug had some black soot, was wet, and smelled like gasoline. No codes. Plugs and coils have <10K miles on them. Intake valves cleaned a couple of weeks ago. Car has 65K miles.
Thanks to Joshboody, jdbretz, dzenno, and themyst for all the help with diagnosing these issues.
We are thinking it's a leaky or defective cylinder 3 injector. Any chance it could be the O2 sensors?
Note: these are not WOT logs. The car was idling and I just jabbed the accelerator for a second or two to bring the RPMs up to ~3K and then let off.
