Still getting lean the longer I run the car. My untrained eyes can't spot anything in the tune. I'm guessing...either a sensor is losing resistance as it gets heat soaked, or the injectors. The ECT is stable, but the wideband is seeing lean creep in the longer I drive. Wish I had a fuel pressure gauge I could use when driving. My harbor freight gauge show 63psi at idle. Fuel pump is fairly new aem e85 pump.
