I bought a 1988 Civic hatchback with a '95 del Sol VTEC engine in it. It's got the original ECU. It had several error codes that I tracked down because I thought they were causing the emission problems, but it is still failing emissions for high HC and CO. Compression is good, 180 psi in all cylinders. The injectors appear to be older type, resistance is 2.5 ohms across the terminals instead of 12 ohms like in my stock del Sol. Injector wires go to a resistor block. Voltage at the injectors is 0.5 at idle, 2.0 volts at higher throttle. The engine runs great, no rough idle, good acceleration. Just bad emissions. CO is over 6%! Any help is appreciated.
