I’m working on my crv. It was driving fine until one day it started hesitating under acceleration. MIL came on for p0300. I have fuel and I have spark. Fuel pressure is at about 45-50psi. Check compression at each cylinder and all are within spec. Did a leak down test on wash cyclinder and they call passed. I checked timing and engine is still in timing. Any input would be greatly appreciated. Thanks!!
This is video of a Honda intermittently losing spark. This one has an external coil,(5 plug wires on the cap) I think your CRV has it in the distributer cap, (4 plug wires on the cap) but I could be wrong about that.
And this one I believe is more like your system, but it is a no start. It is a good video showing the checks on the distributer with a test light and a scope.
