Anyone ever had a vehicle fail its emissions test?

My first car did. It didn't fail because it was killing the environment, it failed because their computer wouldn't establish a connection to my car. I replaced my car's obd2 port and computer, still no go. I spent enough to get a cost waiver for that year. Two years later they expected me to spend a small fortune again.

On a diesel yes. Just added a can of forte in the tank. Revved the ass out of it in 3rd for a bit and cleared out all the crap. Emissions passed. But that was a few years back.

Long,long time ago when i lived in NJ but here in Florida it's a joke. I've seen vehicles here belching so much smoke,they could've worked for the mosquito control commission.

Ya there was a time I failed because the car hadn't been driven enough for the computer to clear all the codes

Yes, multiple times. Had it turned up and it still didn't pass. Finally got rid of it.

Way back in the day when I drove junker cars

Yeah my old truck and cost me $750 to get it to pass

South Carolina doesn't require inspections

In Germany. It was disturbing the sand on the ground.

Yes is this in Texas ?
