That's a bummer. Do you still have the old injectors? I wonder if you could send out for rebuilding on the cheap. If not, when does it have to pass emissions again?
Yeah most sane states just plug in to the obd port. States that had inspection stations with sniffers already set up probably didn't want to get rid of them as private businesses had already invested in the equipment. I'm looking into semi retirement in New Mexico and they smog test in the county that I would be living in. There are dozens of testing locations in Albuquerque alone. I don't see that changing as dozens of businesses would be closed. The obd check should have been the gold standard from the beginning.
I now wants to randomly die at stop lights after its warmed up. I suspect that there are other issues
The egr is $300, the knockoff fuel injectors got me past emissions but it's now dying at idle. OEM injectors are $198 apiece, the iac is $84-$150 to replace.
In Colorado there's no emissions testing for the first 6-7 years, then an obd plug-in for 5 years or so then a dyno drive test. Heavy trucks and 1981 and older get a static tail pipe test. Then hybrids and certain vehicles i.e. long wheelbase, and a few vehicles that can't have traction control turned off only get obd tests. For some reason the Corvette ZO6 is obd only yet other Corvettes are a drive test.
