Cylinder#1 running rich

Recommended Posts

Own a 2003 Honda civic si ep3, have a cylinder#1 running rich it has the ka20 engine, I found the injector not performing at it's best I replaced it still running rich replaced the coil and plug and drove it and rechecked the plug and the plug is black and the rest are normal, haven't did a noid test yet or double checked the spark output I also did a compression check and numbers were normal. I was starting to think if there is a wiring issue to that circuit has anyone come across this issue?
