Default Re: [Update- PASS] '93 civic failed emission or suspicious emision test ?

What happen, what i did and PASS results follow.

First emmisions test failed. Tester had a difficult time geting a
stable tach reading.
Car died while driving two days later, would not re-start, or
fire. Car had a very weak spark (as tested with my hand).
Tested coil with Ohm meter at ~ 8 kOhms it was in replace range.

I replaced ignition coil, replaced plug wires, I cleaned the
rotor and cap terminals, I changed the plugs, replaced the PCV
valve and put in a new engine air filter. Then i took for my
free retest.

2009 **( RE-TEST )** numbers
===========================
....................25/25 test............50/15
--------------------------...........---------
HC ppm .........60....................54
CO %.............0.13 .................0.15
NOx ppm.......168...................146
RPM..............2084.................1913
CO + CO2 %....15.1...............15.1

So not too bad
Thanks to groups for helping.
