I have a 1998 SL1 SOHC that is not passing the "check engine light"\nportion of the CA smog test. I got it from a charitable organization\nwith about 135k miles on it. The mechanic for the organization\ninstalled a new water pump and catalytic converter, and reconnected a\nsensor that was causing the engine light to come on. Since then, the\nengine light has been working normally (coming on at start, then going\nout), but it won't pass the test. The first time it failed, the tech\ntold me to drive it for 50-60 miles at all different speeds, then bring\nit back. It failed again, so he told me to drive it more. I put over\n200 miles on it and it still failed. I finally took it to Autozone and\nborrowed their OBDII tester. The tester showed "no codes", but the\nmonitors show the following: Misfire: ready; Fuel Sys: ready;\nComprehens: ready; Catalyst: NOT READY; Heated Cat: NA; Evap Sys: NOT\nREADY; Sec Air: NA; A/C Refrig: NA; O2 Sensor: NOT READY; H02 Sensor:\nReady; EGR Sys: NOT READY. On the advice of a local Saturn tech, I\ndisconnected the battery for a couple minutes to clear the monitors,\nreconnected, and again drove it at all different speeds for over 70\nmiles. I ran the OBDII tester again and it gave the same results.\n\nAlso, the 25mph emissions test results from the 1st two tests passed,\nbut failed on the third, showing elevated NO and HC (the HC was still\nwithin passing range, but was 22ppm on test 3, compared to 5ppm on tests\n1 and 2). The NO was 163ppm on test 1, 445ppm on test 2, and 1186ppm\n(failing) on test 3.\n\nAside from "chugging" when I first start the car cold, the engine runs\npretty smooth. What do I need to do to resolve the Not Ready monitors,\nand could what's causing them to not go ready also be causing the issues\nwith the elevated HC and NO emissions?\n\nthanks!
