Default Compression test results. Need help! 95 Civic EX
I did a compression check on all 4 cylinders and i was wondering if someone could tell me what the results mean. It has a very bad idle problem if that helps at all. boggy/low idle to be exact.

Cylinder #1: 200psi
Cylinder #2: 180psi
Cylinder #3: 160psi
Cylinder #4: 120psi

Also, there seems to be no fuel getting to cylinder #3.

the leakdown will show where the leak occurs. the problem could be of many, valves, rings, intercylinder leak.

Does the car blow white smoke?

Make sure that injector is receiving power. If it is, most likely that injector
is bad or plugged.

Well 4 is really low, chances are bad piston ring at least.
