Gas Mileage Questions

'98 GTP OBDII
But one thing, the Injectors, timming etc only shut off cause I let off after a WOT run at a higher RPM. If im just cruising on the highway taken it easy and let off the RPM’s would drop and the converter will unlock which will force the car into idle and injectors, timming etc are on.

Edit: after looking at some more scans it seems the only time fuel is shut off is when timming drops to 0. Doesnt matter what the TP% is. As long as I have spark fuel is on. But spark doesnt drop to 0 unless TP% drops to 0 after quick drop from a high % basicly only after I do WOT run and let off the gas quick which follows with wideband reading AIR
