I'm a little bummed today. so i did transfer of title today and i was required to smog. well my 80 d50 failed emission. dang California and its emission test. Here are my numbers
NO (PPM)
10MPH PASS
25MPH MAX(1383) MEAS(1404) FAIL

i didn't really pay attention to my oil service either but it was over 1000 miles. so after i failed i went and did a oil change a air filter(old one was dirty and brown) and spark plugs and im going to go try it again tomorrow.

what i did notice though when changing plugs which where autolite plugs i noticed the tips where really white..... what does that mean. the truck runs fine. like no shaking no weird noises or hesitation when driving. crossing my fingers for tomorrow. any input is really appreciated
thanks michael
