So about two weekends ago I went to drive my 96' GSX and it had turned over but once I backed up the CEL came on and it began to be choppy, so I pulled back into my parking spot. Pulled the code and got p0302. so I went and replaced all the plugs and wires but noticed that my oil cap wasn't sealing. So I pulled that off to find that the nut and the piece of metal that goes on there was gone. So It sat until I got some new tools and I pulled the valve cover off to find the piece of metal and the nut inside. I removed both. Put everything back together today and started her up. She started but sounded weird. No CEL anymore. So I tried to reverse and it died once and it had made a pop sound. and the idle was super strange and rough at 1500rpms and the car would shake a bit at 1500rpms and the shaking would go away if I revved it to 2k. Could this be that the spark plugs aren't tight enough? Any help would be great. I really wanna get her back to 100% again. The only mods done are vrspeed fmic, hallman manual boost controller, hard intercooler piping, 1g bov, and a 14b. Rest of the car is stock.
