Hey,

I just bought a 1988 V8 Volante. I cant seem to pass emissions do to the CO % the limit is .30 and I seem to be putting out 4.63. I cannot register the car til it passes, any thoughts or suggestions would be appreciated. Only thing I could think of would be an O2 sensor but not sure if this car is equipped with one. And I let the car warm up fully before testing.

Thanks,

Steve

Your car could be running rich on fuel. Dont think you can reprogram the engine control unit on your car via laptop on the model you have. First, you would need a lambda probe to see your air/fuel ratios, take a look at those. If they are low (lambdas significantly below 1), you are running rich on fuel, maybe should consider a different engine control unit or allow more air to mix in with the fuel you have.

Also rev the engine a bit before testing it, rahter than testing it straight up. Warmer temperatures will allow a high displacement, high performance engine run better. However, you got a big N/A engine designed for performance, so expect it to run a little bit rich.
