Just bought a 88 Corolla with 90k on 1.6 carburated engine. Failed Emission test, for the second time, too high on the carbon monoxide. After the first fail, I changed plugs, wires, adjusted idle, the car runs fine. Any ideas? Maybe O2 sensor? Thx, in advance for any help. Help me out and I'll send donation.
