1.6L Manual Civic 1998 - 116K
I just moved to Cali. Before coming out, I had some work including timing belt replaced.
Upon arrival I had a smog test and failed. Had some more work done and failed.
First Test-
15 mph 1564 rpm
HC (max 64, ave 9, ME- 63)
CO% (max .55, ave .02, ME .27)
NO PPM (max 477, ave 57, ME 0388)
25 MPH 1820 RPM
HC (max 47, ave 7, ME 50) <-- FAIL
CO% (Max .54, ave .03, ME .77) <-- FAIL
NO (764, 50, 0392)
After the first test, my check engine light came on within a day of leaving, it had done this before. I had the oil changed, replaced my plugs, plug wires, and cap. I also added a fuel additive and put 91 octane gas in. I drove around for 20 min in the city before going to have test done. I had the test done in the early morning. My car did sit not used for about 20 min before he finished the test he was working on.
Second Test-
15 mph 1729 rpm
HC (max 64, ave 9, ME- 42)
CO% (max .55, ave .02, ME .32)
NO PPM (max 477, ave 57, ME 0370)
25 MPH 2730 RPM
HC (max 47, ave 7, ME 19)
CO% (Max .54, ave .03, ME .65) <-- FAIL
NO (764, 50, 0349)
The car is idling much better again. I knew my car was not running as well before and the gas mileage was down. Its clearly running much better but all the changes are costing me. I need to get this right.
Also, why would my rpm's at 25 mph go up to 2730 when the car is now firing better? What is causing my test failure. I'm sure my car is running well now, but need to pass this test. I'm shocked I'm coming in so much above the averages.
