1987 300E just failed California Smog Test
Hello
I just failed smog. See the results below. 4 or 6 years ago I failed and replaced the cat and have passed till today. In California we must run a emissions smog check every 2 years.
15 mph results 1772 rpm
%CO2 13.9
%O2 1.6
HC
111 failed max is 110
CO
.19 passed
NO
403 passed
25 mph results 1770 rpm
%CO2 13.8
%O2 1.5
HC
73 passed max is 77
CO
.16
NO
239
I am thinking of shorting the R16/1 reference resistor. This will retard the timing, will also plug the EZL vacuum line. Maybe also do an oil change as I know the car burns alot of oil. And then go for a retest.
Ideas or suggestions?
Thanks!
