Compression test results / misfire codes 03 civic lx
I have been getting a random misfire code, I tried the basic plugs and coil tests with no luck. I did a compression test and the results are as such;
cyl 4: 121psi
cyl 3: 210psi
cyl 2: 173psi
cyl 1: 210psi
Now I'm a little rusty and been out of the car scene a little but am I correct in assuming that timing is off? I believe the pressure should be 170-180psi and if that's the case then this may be causing my misfire. Can anyone provide insight? Thanks in advance!

Random mis-fire codes for all cylinders?
Service manual says at least 135psi with a 28psi variance. That means cyl 4 could be in spec but, it being so far off from the others I'm leaning towards timing like you said.
