I have a question. I got a 93 honda del sol SI, D16z6, it has the stock piping with a tsudo muffler. When i shift, it pops. its not too load but it gets annoying after awhile. Someone said to mess with my timing so i set it to about the middle because it was all the way advanced. Does anyone know anything about jumping my service connectors as i have heard this could help it, and where my service connector would be in my car?
