I adjusted exhaust for a better fit at the collectors, added a supplemental ground wire and re-torqued my intake manifold. Did a data log and actually drove on the pavement at a whole 64 mph lol. Seemed to do better wideband seemed to follow what the fuel trims were doing. Stft are still mostly negative and stay together for the most part. I’m still getting an occasional positive like 27ish spike. I’d say it happened 10 or less times in 20 minutes. I’m thinking I may have an intermittent leak with the msd one intake port because I’m not getting any misfire history when I scan for dtc that would point to bad injector or spark.
Speaking of dtc, after the run today there was zero Codes, nothing even pending So that was awesome and means oil pressure issue is over for good I think.
