Where is your timing at?

What car is this? Happen to be a Vx/Hx? Is it stock?

 

its a 93 dx coupe
i/h/e
all carb
i didnt see the timing

 

take your vin# off dude... i pmed your plates. remember what city you live in (i sent that to you too)... thiefs among you bud... keep it safe.. always.

 

check timing

 

weld another cat on there.

 

since your in CA....

go to those ghetto smog shops and pay 'em off...they'll pass you. they dunt even need your car to smog. they smog their own car .

 

Seafoam your car. I read it helps with emissions. Also maybe retard your timing. Also look into those fuel additives that guarantee you to pass emissions.

Also what kind of cat are you using?

 

It seems u are running rich. Consider the O2 sensor. And get a tune up

ppm is parts per million... your NO is high... (NOx)

did you not read the thread?

please use the info given to you next time....

 

Leave California. Come to Florida or like state. Stupid demo...nevermind.

 

RETARD TIMING to between 14-18btdc

I bet with those numbers, youre probably running at 19+ btdc.

try the Methanol and Ethanol trick near the bottom of the page

 

Damn, your pegged as a 'gross polluter', can only go to 'TEST ONLY' facility- less likely to get clean piped at 1 of those. I agree to retard your timing- has to be within limits though. Also, check your EGR- biggest culprit of high NOx. What's the other readings, HC's, CO, CO2? Will be able to give you more insight
