Hey guys it's been awhile since I've been on here. So I did some research here and need more support. I now have a 95 nissan 240sx stock ka24de recently started miss firing was drivable from work to my house (12 miies). No check engine light but my obd2 code reader threw a p0301(cylinder 1 miss fire) change new plugs and wire but still miss fire. I'm guessing next thing would be fuel related injectors, fuel filter or maybe fuel pump...??? Need help has anyone encountered the same problem?

Still showing a misfire come to find out my friend got the wrong injector 370cc instead of 270cc. So we order a set of 4 just to be safe. We also did leak down/ compression test and it's good at 170psi. Just waiting for these new injectors to come in.
