My GVWR is 8545. That apparently requires the old tail pipe sniffer test. Nobody and I mean nobody has the equipment to do this test. I even called the Pa. state police, they found me one about an hours drive away, lol. I guess most 2500's have a GVWR over 9 or 10,000. Power Wagons don't have that rating requiring them to have the old two step emissions test. Why they can't just do the OBDII test is beyond me!
Dunno, I just figured send U the info. Many Moons ago, had to go thru NJ State At their "approved" garages, where they did the tail pipe, jacked up the front of your car, checked ball joints, checked alignment, headlight alignment, all dat silly chit.
There was another article in there I did not send that reported on the PA Senate working to eliminate some of the smog tests, U may want to research that also.
I'll just stay down here in TX now, LOL.
