I have a new problem. I think I have found out why my crx is such a terd. During my routine engine inspection / checkup I noticed that I have white tipped spark plugs. I asked my brother in-law about this and he told me that it means that my fuel system is running lean. I just am not sure how to fix this problem. 1990 Honda CRX HF with a D15B6 with the following aftermarket parts; cold air tube and filter, SS header and 2.5 in full exhaust with an N1 titanium burnt tip muffler, 10mm plug wires, and NGK V groove plugs. Other aftermarket; 40% short shifter, 245 55 r17 tires and racing rims, front and back top strut braces, and a racing steering wheel.
