1990 Hpnda Crx Si mileage: 187,838 My car fail the smog test...my overall test results for Comprehensive Visual Inspection: PASS and for Functional check: FAIL and Emission Test: FAIL and it said my Inition Timing: 25 fail.... you guys have any idea what the problem.....and also i found the tester error on the paper he put for engine size: 1.5 L so that make the test weight 2250 but my car engine size: 1.6 L and test weight should be 2500 from my pass test. Test at 15 mph fail and 25 mph pass. Is that one of the problem why my test fail because he put a 1.5 L instead a 1.6 L.


Thanks Dee

Suggested Repair

Replace the catalytic converter. The owner confirmed the converter was the cause and the car passed smog after it was addressed. Also verify ignition timing, which failed at 25 degrees, and make sure the test station enters the correct 1.6 L engine size and test weight.

A 1990 Honda CRX Si with 187,838 miles failed smog on the functional check, emissions, and ignition timing at 25 degrees, while the visual inspection passed. It failed at 15 mph and passed at 25 mph. The owner also noted the tester listed a 1.5 L engine and a 2250 test weight instead of the correct 1.6 L and 2500.
