Solved - Misfire on cylinders 1,2,3,5 and 6 exhaust at idle, cat damage at 4k rpms

I'm posting this hoping it will help someone.

I had a misfire at idle, not very noticeable, no SES light. At 2k rpms in 2nd gear or above the engine would stumble. At 3k+ rpms it would even out and feel fine but not quite as much power as it should have. Pulling codes with INPA showed "A" misfire on exhaust side for cylinders 1,2,3,5 and 6 at 640rpms regularly. Eventually it registered a misfire with "cat damage",Digiprog III or kat damage, around 4k rpms which triggered the SES light and eventually limp mode.

Checked the INPA Run Unrest page, It showed cylinder 3 over 1000, other cylinders also showed very high but not over 1000.
Checked the spark plugs, they were 2-3 years old, maybe 40k on them, nothing stood out. Went ahead and replaced them. No change.
Purchased an ignition coil from advanced auto, carquest if that matters, for testing purposes, fits, but clamp doesn't fit. Bremi on order.
Replaced cylinder 3 ignition coil, no change, cylinder 1, no change, 5 no change.
Finally replaced the cylinder 6 ignition coil,Vagcom 15.7 and the misfire is gone along with the high Run Unrest numbers across the board.

I searched on the board and saw some others with similar issues but theirs either pointed directly to the culprit or did in a round about way. I don't think mine showed any indication of being cylinder 6 as the culprit. I think the lesson here is, check them all.

No eeprom option in OBDSTAR X100 pro, how to use EEPROM PIC adapter?

Starts with my question: how to use the eeprom adapter of OBDSTAR X-100 PRO? There is no EEPROM MENU in the handheld….. But I bought X100 pro with C+D+E configuration included in package two EEPROM adapter.

There is no eeprom option in my device.

Finally, I sort it out, I did like this:

Just contact my supplier then give serials they will activate eeprom for me.
Must return to the OBDSTAR official site www.obdstar.com download section then get the new display for my x100pro.

Then connect X100 pro key programmer with vehicle or power supply and turn on the machine, finally connect the EEPROM adapter or chip with the X-100 pro main unit. Follow the system operation and select EEPROM function

After that everything will be ok

Step-by-step instruction on how to use EEPROM PIC adapter to read write with X-100 pro. Please reading following parts

FYI, EEPROM PIC adapter is available now and no need buy separate on the dealer site.

Eeprom PIC adapter connected to x100 pro and in working status
