I wish someone out there knew how to tweat an ECU as many of us have experienced these spikes but they dont stick for the longterm. I have replaced most components trying to get to 30mpgs. My 94 had a 33mpg spike one time just after I changed an air cleaner... That was only on one tank.
It must be all in the sensors, where the ECUs get the info to adjust on?
