Hey everyone got a question on my 03 honda civic so ep3, I am the third owner and noticed the #1 cylinder runs rich so dug into it and I replaced the injector, spark plug and coil and drove it rechecked that and all cylinders the #1 plug is black I also did a compression check and all cylinders are at 175, I haven't gotten into any wiring yet but if that's the case I am not afraid to tackle that area just wasn't sure if anyone has come across this issue. Any comments appreciated.

Have you done a leak down test? 175 is a little on the low side if you tested correctly (Engine at Operating temp with throttle wide open)
