Emission inspection falilure


Vehicle Information: Model: Carrera - Cab; Year: 1989; Body Type: Convertible; Engine (type, size, modifications): 3.2; Total Mileage: 69119;

I my 1989 failed Georgia emissions . Everything passed except NO .I was told I probably need to replace the converter which I did . My CO reading improved , however it was not a issue . My NO reading actually worsened ! Since I do most all repairs myself , I'm determined to resolve myself if possible before throwing in the towel . Any suggestions ?Thanks Tony Monico
