Hello, I am having an issue that I cannot quite figure out. I am fairly new to tuning, and I do not have a Wide band. Anyways I was messing with the tranny trying to make it shift down with less throttle. well i went on a test run and hit about 80 at wide open throttle and got a P0300 Random Misfire (Immature) code that did not set a light but flashed and went away. since then my 02 sensors have started going rich and maxing my stfts negative and making my ltfts drop negative. At the same time everythinge else seems to go haywire and I would appreciate someone else's input. It appears to be getting worse over time and on top of this the rear o2 sensors are acting strange too. I will post both data logs, the first being the one where I had the misfire code, the second being where everything is acting up. Any input would be helpful, thanks in advance.
