i tried to smog my 95 GSX to potentially sell it. it's pretty much bone stock. i have 660cc denso, evo 9 pump, and DSMLink with correct deadtime/etc for the injectors.
I PASS the 2500rpm TEST! flying colors! As well as every other check.
but fail idle test?!?!
I must admit my idle was weird. On cold starts it would idle high and settle. Turn it off then turn it on shortly after sometimes you need to give it some as to keep it alive. I knew this and I kept the car on. But stupid tech turn it off. When he started it again, it was having a hard time idle even dying, he had to give it gas. So its not dying anymore but I could tell it was idling really low.
Well I failed the idle test.
Could I pass if I raise the idle on dsmlink to 900. I changed the ISC and its much better. Smog said the bad idle control kept on messing up the trims because it was wanting to die, etc etc. Don't remember the exact stuff.
