Hi, you can spend a week trying to figure out what is the problem without any spare parts.

This sound fuel related, i agree. So find a shop or buy a fuel pressure tester. I feel you have a bad injector (even if new) or a faulty fuel pressure regulator. You can also remove the fuel injector rail and look at the spray pattern.

Second choice: ECU going bad. Tyipical lately on Digifan.

Third one: something related to the Temp 2 sender, this one can be bypass with a cheap resistor.

Fourth choice, distributor related.

I'm sure you have unplug the OS??
