I'm chasing a similar issue with cyl #4

Mine is only missing under wot or heavy load. If I drive it easy, it doesn't miss.

Swapped things around, same as you. Problem persists.

- Try a different ECM. There is a power chip in there that sometimes fails, per Steve Eiche. - Trango 2015-06-29 12:19:54 (170 views)
  - ECM as in ECU? or the units on the airbox? (forum search points ECM to both) - serf2k 2015-06-29 13:33:37 (179 views)
    - ECM/ECU as in the thing in the box next to the battery on the firewall that makes everything work. - Trango 2015-06-29 14:18:11 (160 views)
      - Hmmm.....all I need is a an ECU from a 6-speed '01....   -  serf2k  2015-06-29 16:56:32 (175 views)
        
        You can use any ECU from an A6 or S4 from 2001 to 2002. I can help you recode it.   -  silva  2015-07-03 20:10:11 (174 views)
        
        You don't say? Soooo...if I had an ECU from an '01 A6 2.8? Like...say....my son's?  -  serf2k  2015-07-03 23:50:51 (132 views)
        
        Has to be an ECU out of a 2.7T car.   -  silva  2015-07-04 22:30:43 (117 views)
        
        That would make more sense...I'll find one.   -  serf2k  2015-07-05 10:48:26 (183 views)
    - Wait. Did you swap wires between the ICMs? - Econguy 2015-06-29 13:41:59 (206 views)
      - Yep, one of the first things I did since it's pretty easy. No change from Cylinder 5.   -  serf2k  2015-06-29 13:48:54 (153 views)
        
        I figured :)  -  Econguy  2015-06-29 14:26:54 (155 views)
        
        Nothing under any load, only at idle.....  -  serf2k  2015-06-29 16:54:37 (177 views)
- Derwin is having the same problem on his b5s4. Replaced everything... Poor guy - chaloux 2015-06-29 07:33:30 (179 views)
- When is the last time you had that valve cover off...? - stuklr 2015-06-28 23:09:24 (203 views)
  - Just before Carlisle. Nothing looked amiss. - serf2k 2015-06-29 08:14:29 (226 views)
- Have you looked down the hole? - FrenchToast 2015-06-28 17:46:12 (222 views)
  - Check wiring and make sure you have 12V at the injector,leave coil loose and lift slightly, you - kinderutz 2015-06-28 18:07:27 (250 views)
- Worst case scenario: did you check compression? - Econguy 2015-06-28 17:08:05 (200 views)
  - Probably the next step - may need to manufacture an extension for my pressure gauge. - serf2k 2015-06-29 08:15:47 (210 views)
