My sister has a 2001 Honda CRV and was getting a CEL, the codes were, P0303, P0304, P0300, and P1399. The plugs and wires are fairly new, they are both NGK. I just replaced the distributor hoping that would remedy the problem, but when timing it with the timing light, I have the distributor rocked all the way forward and cannot get the orange/red mark to line up... If I rock it back, the orange/red mark gets even farther away from the alignment mark... It has always idled kind of rough, valves were just adjusted and they were almost all within spec. So I'm stumped with the cel's and not having enough adjustment on the distributor to time it correctly.. Ane help would be greatly appreciated!
