Need some help determining if emision failed due to real problem and how to fix
*OR* was this a suspect emission tester and i just wait for different tester ? what to do ?I am original owner of '93 civic Si HB 205,450 miles.
I do most all basic maintenence (filters/oil/etc) and repairs (eg. brake pads/ radiator replace/master cylinder replace/ ignitor replace/ replace distributor, etc ) honda dealer gets the bigger invasive stuff like timing belt, water pumps, clutch ...
The car has passed emissions by no small margins till this year and it FAILED miserably ? *BUT* only on the 25/25 test ?
Only 5,400 highway miles were put on the car from 2008 test to
2009 test.2009 numbers =========================== ...................25/25 test............50/15
----------------------................--------- HC ppm .....288.....................65 CO %..........9.38 **...............0.20 NOx ppm....345.....................255 RPM............2718..................1971 CO + CO2 %....18.3..............15.1
2008 numbers =========================== ....................25/25 test...........50/15-------------------------.............--------- HC ppm .....73........................70 CO %..........0.22.....................0.23 NOx ppm...236......................212 RPM...........2100.....................1925 CO + CO2 % 15.1.................15.1
Ques 1: Does this test failure look like real (possible) numbers ? that is, how does it fail 25/25 ***SO *** bad and not the 50/15 ?
Ques 2: if these are real numbers then what repair am i looking to fix this ?
Ques 3: Can the tester muck up the test and get that 25/25 test failure ? Not that he wanted to muck it up but maybe a little incompetent because he had these several problems ...
- Could not get the tack sensor in the right place , kept moving it all around like on top dash , center dash, on mirror , under dash, on windshield, on the hood , under the hood ? could not seem to find a place that gave good tach readings and kept saying, "your RPM is bad"
- He tried the clip on tach wire but could not get the wire connected to machine correctly.
- 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
