Could be wiring loom for injectors. Sits in oil inside the tappet cover. Known to fail and cause misfiring, implausible signals, electrical issues.

I change the wiring loom also another thing I figured is that the car was charging low than the required 12v can it be the ecu has blown mybe it doesn't supply the correct signal to the injectors but there is funny smell in it

Did you check ground connections?

One by fuse box, one by ecu under cowling that powers ecu, one in interior by footwell. There is a couple more. Maybe bad ground is causing your misfire as well.

Lower power usually does not blow ECUs unless power spiked up and damaged it somehow.
