View Full Version : Cheated the second time.....but passed

09-10-2009, 12:24 PM
failed the first test but, not by much.
HC ppm was 19 with 52 being a pass
CO% was .15 with .29 being a pass
NO ppm was 549 with 385 being a pass
@ 2000 rpm test
curb idle was almost nonexistent in test. easy pass.

by far better this time around than the 3800 NOX readings previous years.

got the guy to do a second test with the plug pulled. i didn't know you can't touch anything under the hood while doing a retest. (guy was yelling at me ) government regulations. so i pretended to close the hood and quickly pulled the plug. idle went down ever so slightly and then stabalized. -the guys never noticed.

second test @ 2000 rpm 2nd gear.
HC ppm 11 with 52 being a pass
CO% was .12 with .29 being a pass
NOx was 187 with 385 being a pass

dilution stayed the same at 14.6
hope this helps anyone having the same troubles with NOx readings.

What "plug" are you talking about? I have to get tested by the first week of October

the spout connection up by the DIS. you wil notice a couple of wires that terminate at a connection with a plug in the end of it. pull that out. but, only for the test and then put it back in when you get down the street.

Did you pull the SPOUT or OCTANE plug, to pass? There in the same location.

the plug i pulled is right on top of the dis ignition control module. as far as i know, on the 92's it's the only plug in that location. i thought the octane plug is on fire wall on all these cars. i'll check that out though
