-02s also use the HO2S sensors to determine A/F, but the MAF plays a part in it as well as effecting the transmission shift pressure and shift and tc schedule.
I had never heard of a 4.6 panther having a PCV solenoid, though, I know 05+ PCVs are heated and use quick connect couplings now as well as the screw-in base like all 03+. I have an 05+ PCV in the garage somewhere which just has a two wire hookup which the EVTM lists for the heating coil inside. The plenum has no solenoid for PCV on it. Where is it?
