I'm attaching this FoMoCo 2007 MY OBDII Summary sheet below to help you to better understand why you're seeing what you're seeing concerning the misfire monitor showing no last counts......what most of you are looking at to determine # of cyl misfires.
From my intuition, your car is a 07 MY & is why I've attached this FoMoCo OBDII Summary for a Ford 07 MY vehicle (includes all 07 S197's.....).
Go to pg 15 thru 16 of this report & read it all.............this is Ford explaining how the Spanish Oaks PCM detects & records misfires........and more importantly, what 1 HAS to do\perform once the batt has been disconnected OR the PCM's KAM gets reset (cleared) to RECALIBRATE the CKP sensor to trigger wheel so PCM can know the difference between a crank accel velocity pattern under load vs a crank decel velocity pattern under full DFCO operation BEFORE the PCM will start RECORDING misfires to Mode 6..........
This recalibration routine (60\40 Misfire Monitor recalibration) is built into the Spanish Oaks PCM calibration thus you don't need a separate tool to do this..........like all Ford vehicles >2010 do, but you DO need to perform this as it is laid out in this summary.
To help shorten this for you.............the 1st time you accel past 60 MPH in either 4th or 5th gear (manual) or D for autos (I'd disable overdrive prior so trans will stop in 4th gear.....), take your foot off APP & let engine coast & enter DFCO then DON'T touch the APP, brake pedal (auto or manual) or clutch pedal\gear shift (manual only) again until the vehicle MPH drops below 40 MPH then use the APP only & accel back above 60 MPH then repeat the prior instructions.........do this for a minimum of 3 consecutive times for Spanish Oaks PCM to complete this & save the learned CKP to trigger wheel pattern in the onboard AICE chip......then the Spanish Oaks PCM will start recording misfires into Mode 6 thus will be saved. This version I have found works the best & will cleanly complete every time it is done as explained.
For a manual trans (my car is a manual), I've found this works better\cleaner in 4th gear than 5th gear, even though 5th gear imparts more load on engine during this procedure.
Note: this is best done using a very remote stretch of road w\ very little traffic to interfere w\ procedure application..........so be advised.
I have a LOT of datalogs that will clearly demonstrate\ have recorded this showing the Spanish Oaks PCM not recording a single misfire event during the initial datalog drive cycle post KAM reset from tune reflash.......until after I've performed this procedure..........thus I know of what I say here.
If this isn't done, the Spanish Oaks PCM will only show all 0's for misfire counts........thus will never show any MILs for misfires...........until this procedure is completed & pattern is saved.
This is the main reason why you're not seeing misfires at this time..........you haven't done this recalibration yet.
Anyone that tries to tell you that this procedure is fully automated thus you don't need to do anything post batt disconnect or KAM reset.........is not exactly telling you the truth.
Now..................what work did you just finished doing..........with the batt disconnected while doing it?
This is showing to not be well understood among the community...............I have posted about this several times in other threads (w\ the link to fordmotorcraftservices.com provided & several copies of various MY Ford OBDII Summary sheets as well........like this 1.......), but the message is not getting learned\received.
Hope this helps you.
