Hey guys, my friend took his car to the CA B.A.R with an LS Swap and everything seemed to pass fine. The car is a 94 EG hatch and the motor is a 96 LS. The visual inspection failed only due to DC headers that the previous owner had. So we replaced them with stock headers and have an appointment for today at 1:30. I took the smog results to a smog tech and he said that it also failed due to maybe having a misfire. Here are the results.

15 MPH:
RPM - 1944
MEAS %CO2 - 15.0
MEAS %O2 - 0.0
MAX HC (PPM) - 92 FAILED
AVE HC (PPM) - 21
MEAS (PPM) - 160 FAILED
MAX CO (%) .55
AVE CO (%) - .06
MEAS CO (%) - .48
MAX NO (PPM) - 716 FAILED
AVE NO (PPM) - 150
MEAS NO (PPM) - 1325 FAILED RESLTS = FAILED

25 MPH:
RPM - 2235
MEAS %CO2 - 15.4
MEAS %O2 - 0.0
MAX HC (PPM) - 57 FAILED
AVE HC (PPM) - 13
MEAS (PPM) - 68 FAILED
MAX CO (%) .54
AVE CO (%) - .05
MEAS CO (%) - .06
MAX NO (PPM) - 764
AVE NO (PPM) - 136
MEAS NO (PPM) - 53 RESULTS = FAILED

Sorry for the long post but I was wondering if any smog techs out there can help me find out what I need to do to fix those results. Not too sure if this is in the right forum either.

First and foremost, make sure you have a GOOD converter installed. Secondly, it looks like you have a rich misfire. What ECU are you running and is it modifed/chipped? Are you using NGK plugs?

Well the previous owner had told me it was a new cat. It's running a p75 unchipped and I bought some new NGK platinums before the test.

your running a platnium tipped plug?

if so that is your problem right there. I dont care what anyone else says if your car did not come from the factory with them dont friggin use them!!! thery require a higher amount of energy to fire and on most stock ignitions it will create a misfire!!!

I learned this first hand while in school to be an auto tech.

Oright thanks, so just use the stock ones none platinum then?

Your in CA....it may be a new cat but it may not be CA OBD2 compliant for this state.
