The "low" setting is at 50hz. "high" is at 150.

Turning off flex seemed to fix the issue up until today. I took the mid pipe off to make some adjustments and now the car runs like its on 2 cylinders. Barely starts and will only sorta run for a few seconds before dying. I don't really know how this is possible. The 02 shouldn't be pulling a vacuum at this low of an rpm/cranking.

Logs attached.

2 cylinder mis #1.mlg
2 cyl mis #2.mlg

 

Check your grounds.

 

grounds all look ok. Spark test modes check out. plugs are soaked. So.... confused.

 

Car runs now. I suspect one of the plug boots might have popped out. The only thing I did was pull plugs for spark output test mode to confirm I had spark. It checked out so i out it back together and it fired up.

 

Ok so I think the plugs just fouled out from all of the cold starts the car has been through. It runs pig rich when cold so I should probably lean it out a bit.
