Had one-off bucking during a WOT 3rd gear pull at about 4000 rpm yesterday. - TheCrispyNoodle 2017-05-22 03:08:30 (596 views)
- One-off meaning you have tried to recreate the situation and there was no bucking? - ThetaTau87 2017-05-22 22:22:45 (536 views)
  - Yes it did it once, has not recurred. I do carry a spare coil in the car, so if it is that and it - TheCrispyNoodle 2017-05-23 08:13:55 (540 views)
    - I've never heard of a coil causing bucking. Ignition issues cause a stumble that is much less - ThetaTau87 2017-05-23 13:31:40 (538 views)
      - It was pretty severe, much worse than just a loss of power, lasted fraction of second though. No DTC  -  TheCrispyNoodle  2017-05-23 15:13:08 (547 views)
        
        How can it be worse than a loss of power? A partial loss of power that you could incur if one  -  scarman  2017-05-24 00:03:38 (547 views)
        
        Thermal fuses on ignition circuit maybe?   -  TheCrispyNoodle  2017-05-23 15:18:22 (483 views)
        
        So change them (the ones above the ECU) to spades.   -  UrS4boy  2017-05-23 16:08:55 (530 views)
- Fundamentally I am asking 2 questions: - TheCrispyNoodle 2017-05-22 13:53:42 (583 views)
  - Perhaps not a DTC that you would associate directly with the fuel cut-off, and maybe a faulty sensor - scarman 2017-05-24 00:21:12 (484 views)
  - I have the same setup (coil wise) and if it was mine, I wouldn't be messing with the coils... - running_cold924 2017-05-22 14:01:07 (569 views)

  - Stock wastegate screw position. Bent 2 hex keys trying to move it and gave up. - TheCrispyNoodle 2017-05-22 13:45:22 (544 views)
    - There is some thread locker in there. Needs heat sometimes. And a proper hex allen socket. - UrS4boy 2017-05-22 13:57:10 (529 views)
- Fwiw; GAP has oem red top coils for $19 - airbil 2017-05-22 08:12:32 (536 views)
- How long have the plugs been in there? - running_cold924 2017-05-22 06:01:10 (517 views)
  - I run Bosch FR5DTC copper tri-node plugs so change them regularly. This lot been in < 1000 miles - TheCrispyNoodle 2017-05-22 07:46:07 (558 views)
    - You may want to try a sigle electrode plug, just gap it at .026 - running_cold924 2017-05-22 09:56:10 (634 views)
      - I like my Bosch pin gap tool. Works well on those multi-prong plugs.   -  MarvelousS4  2017-05-22 11:37:02 (621 views)
        
        What exactly is that style gap tool called. I'm not finding anything similar online.   -  ThetaTau87  2017-05-22 22:32:44 (561 views)
        
        Ah, interesting. Did you get yours off worldpac? or?   -  running_cold924  2017-05-22 12:31:45 (527 views)
        
        Too long ago, Amazon has them now.   -  MarvelousS4  2017-05-22 14:53:06 (492 views)
- Should add I am running a stage 1+ motronic with no dwell time adjustment, - TheCrispyNoodle 2017-05-22 03:13:45 (537 views)
  - Not an issue at Stage 1+ *usually*. That is a tracking issue with RS2+ levels. Too much heat. - UrS4boy 2017-05-22 09:53:23 (537 views)
