1990 Honda CR-X HF 1.5L Fuel Injection M/T. My vehicle gets below normal fuel mileage (36 MPG compared to 50-55 MPG) it passed smog here in south California by a hair, being high in both HC and NOx. The engine pings at low speed, hesitates every so often, and one peculiar trait to the problem is that the engine vibrates excessively at idle, and at about 2000-2200 RPM loaded and unloaded it has a "putt - putt" feel as if it were missing, but just fine above that engine speed. Have replaced 02 sensor and spark plugs only. Seems to be running rich. What is your opinion?
have the same problem?
