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

#1

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.

I am original owner of '93 civic Si HB 205,450 miles.

2009 test.

The car has passed emissions by no small margins till this year

- at some point during testing he could not seem to get the
gear
shifted so he left it in 1st and ran the car up to about 20
miles per hour in 1st gear the car was running really loud so i
peeked in at the tach which up around 5000-6000 yes that is
5K-6K
and held it there for about 30 seconds waiting for the machine
to
do something ?

Anyways, i would appreciate some helpful advice on what to fix
or
do please
