I have my del sol with h23block and h22 head and cylinder 4 will not work unless it's over 4000 rpms. Constant spark at all rpms and injectors are spraying. The compression is 160 across the board. Fuel is spraying even through all cylinders and spark is even with all cylinders seems like cylinder 4 is too rich but will come on past 4k rpms. I dont know what's up and I can not figure it out. Also it will work fully sometimes when warming up but then misfires again after its warm. Ecuador is all plugged in and working NO C.E.L. Also. I really need help. I've swapped the dizzy and fuel pressure regulator along with the injector on that cylinder. Cams are both tdc. Maybe a burnt or bent valve. Maybe the rings but the compression is solid at 160 in all cylinders. Ahh I'm so stumped. Anyone helping I would very much appreciate it!!

What ecu are you using? Are you sure your cel works?

A chipped p28. It used to run great and the cel works cuz it came on when I didn't have my tps calibrated right but I fixed it

With what basemap?

Not sure but it's got a p28 and nothing fancy... Would the chip and baseman maybe fail and that's why cuz that doesn't seem to make sense!
