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??
