Missing

[HeMiBoB]

Started missing last night the car has a LOT of mileage but runs well, doesnt burn oil or smoke at all. It went away and now its back...
I have a Diablo Predator Tuner but it didnt show any trouble codes, other than a O2 Sensor, which I have known about. The car idles OK but mostly lugging down low it's miss is the worse.
My wifey's Mercury Gran Marquis shows what cylinder and etc when it was a miss fire, I just replaced a Coil pack.
Is there anyway to run this Diablo Tuner and monitor Live data? It came with the car and has no manual etc.

OK
Retrived Trouble codes..
P0602- Replace PCM .... WTF??
P0605- PCM "ROM" Error
P1211 ???
P1690 ???
P1000 Monitor test Incomplete
P0135- Upstream heated O2 sensor Fault

So I have owned the car for about a month. The car had No Check Engine Light on and ran well, but the clutch was toast...
I install a new clutch setup, of coarse the battery was unhooked.. But has been running well.. running great actually. But I think I broke the O2 Sensor during the clutch job...
I might be able to jerry rig the broken end IDK....
Anyways, the car had the miss as described...

OK Diablo boots up and says P0602 P1211 P1690 P0605 are normal...
The only codes I have then are a P1000, so I just reinstalled the HP tune on the Diablo..
And P0135 which I know is a O2 sensor. I was thinking I could turn this one off with the Programmer.. But not sure....

Miss under load is a common symptom for ignition. Heck your wires and plugs. Then your COP's.

Hmm. P1211 and P1690 don't seem to apply to your car/engine. I believe P1211 (injector control pressure" and P1690 (wastegate solenoid) are for Powerstroke diesel apps. I did a search and found another instance of someone reporting these codes from a Diablo Predator on allfordmustangs:

codes with the predator tune.PO602,PO605,P1211,P1690, - Ford Mustang Forums

It's almost like an upload didn't complete successfully or was corrupted etc. Can you return the car to the OE tune stored in the Predator?

Yes
I actually reloaded the HP tune from the Predator tonight... It still missed however.
