Take a compression test and test for injector pulse on those injectors. If it passes both of those tests, then you may have a couple bad injectors but I suspect compression.
Make sure you actually have spark on those cylinders with a spark tester first.

The injectors are fine as you can smell the fuel. It's that there is no spark from the back 2 on the coilpack. But it's brand new and the old one did the same! I didn't know if it could be ecu alternator or loom?
