92 s13 need help with miss fire

[gilbert240sx]

I have a 92 s13 ka24de the car is blowing a lot of white smoke out the tail pipe it has new injectors and spark plugs but I have a miss fire on cylinders 3 & 4 also I I did an oil change and in less then 30 min there is gas in the oil pan.
Im thinking it might be the ECU or the wire harness what do you guy it can be?

It's the lower o-rings on the injectors.

You need to replace them. Make sure to use vaseline or dielectric on them, like a lot of it, to slip them in. It lubricates them so they don't rip, and don't pinch so they're not quite seated. (the gas won't lubricate them, it doesn't really decrease friction)

It's dumping gas around the ring and flooding those cylinders. Don't run it that way.
