I have been working on a 1994 Saturn SL2 in preparation of Chase going back to college at the end of next week. I have done brakes, changed the oil, replaced the air filter. According to Chase the spark plugs and everything were changed last year so I didn't mess with them since he doesn't put that many miles on the car. He brought it for its emissions test yesterday and failed miserably. His HC (PPM) count was 328 with a limit of 158 and the CO was 2.66 with a limit of 0.84. He's not throwing any codes, but I'm thinking that the bulb may be burnt out. Does anybody have a scanner and ideas of things I can do to get the car ready for re-inspection?
