| and stumbling problems. We have replaced:
1) Spark plugs
2) Fuel filter
3) Fuel pressure regulator
4) Fuel pressure dampener
5) Selin V1 translator to new Selin V2 translator
6) Polar Engineering fuel pump setup and hanger with a single Wallbro fuel pump
7) New PTU
8) Fuel pump relays I've also sent my ECU and Specialty Z chip to Seb and they bench-tested it and plugged it into a test Z and did not run into any drivability problems. The only thing that we have not changed is the TPS and the CAS. Here’s a link to a 12 minute video from Saturday while I was limping my Z home from a local Cars and Coffee about 8 miles away. https://www.youtube.com/watch?v=mHEyRCzd6rw There's pronounced stumbling at the following time indexes: 3:00, 4:30, 5:20, 6:00, 8:00, 9:30, 9:5-, and 11:30. Seb suggested that I plug in a Consult or Nissan DataScan and see if anything comes up. Maybe the TPS is bad? What about the CAS or even O2 sensors. I really want to drive my Z but I have no idea what is causing the issues. TIA
