1989 190e 2.6 failed Ca. smog, help! please
Car has 115K miles.
Does the 1989 190e 2.6 has a EGR valve? didn't see anything coming back from the exhaust like the 93, 300E I had once. 15MPH test RPM 1911 %CO 14.4 %O2 0.0 HC ppm = max 114 Average 31 measured 169 failed CO % = max 0.73 Average 0.10 measured 0.84 failed NO ppm = max 785 Average 237 measured 726 pass 25MPH test RPM 1893 %CO 14.3 %O2 0.0 HC ppm = max 88 Average 20 measured 158 failed CO % = max 0.61 Average 0.09 measured 0.94 failed NO ppm = max 724 Average 199 measured 677 pass Since the failed test I changed the oil, air filter, checked spark plugs, filled up with fresh 91 octane, any other reccomendations before I take it back for the re-test. I read the posts about prior conditioning of the motor to make the cat run hot. Anything that the MB gurus can come up with that could help. Thanks.
