Ok, I changed my oil, filter, and plugs last Saturday, and I'm just curious if these look right. Motor has been in for about a month.
1 month ago - stock U12 ecu - no o2 sensor...ran pig rich and bogged if throttle was depressed too quickly.
3 weeks ago - stock U12 ecu - 300zx o2 sensor...no more rich condition for the most part, still had the bog issue.
2 weeks ago - JWT ECU - 300zx o2 sensor...no rich conditions, no more bogging issue.
1 week ago - Changed plugs, oil (Mobil 1 full synthetic), oem Nissan oil filter.
I'm concerned about the slight pink discoloration and the black deposits at the end of the threads... might be normal for the conditions it experienced, just want to be sure, lemme know what you all think.
