88

1988 Toyota Corolla

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.

The problem is most likely the EGR. It is loaded with carbon. Remove the entire riser and EGR then clean thuroughly with engine cleaner, reinstall. This should solve the problem.
