Got a question that someone came across, my 03 honda civic ep3 has a cylinder#1 issue it runs rich and the rest of the cylinders are good, did a compression check all cylinders are good replaced the injector and coil also the spark plug and still show signs of running rich, I have not checked any wiring yet I was planning on checking the valve lash since it is recommended the engine has 120.000 on it the engine feels strong and I am the third owner any info would be appreciated or questions.
