I been having a misfire issue. So a little history first. I have ran 25psi on e85 with a 20g without misfires. But the car, has always had a random misfire code that it would throw a few times a year. I clear the code and everything is fine. The car ran fine.
When that motor spun a rod bearing, my 6 bolt swap, 2g head, and kiggly trigger switch was dropped in. I have done a blt to 28psi with no leaks. I want to test higher but cant get a tester coupler to stay on for the life of me. Things that changed from the old motor to the new one was HI Z fic injectors, hx35.
My issue is a stutter at higher boost like 20 psi. I can do a pull and hold 10psi fine without issues. I have replaced my fairly new ngk wires with brand new ngk wires. I have tested my coil and it measures within spec. I have tried ngk bpr7es, bpr8es, bpr6es, br7es, and br8es. I have played with the gap from 025 down to 018. The problem doesnt go away. Now is there anything else I should try and check?
The kiggly trigger was to make this so I'd didnt have to do any wiring. I am also using a 95 cas behind the cam gear. When the stutter happens, I dont get a cel. I dont have a way to confirm a misfure other than jumpy rpm in my logs.
