Question about 1992 GMC G2500
I would go to the pharmacy and buy a half gallon of 75% or better isoprople alcohal the run the vehicle to almost empty,then add the alcohal and put just a few gallons of high test in it then drive to your testing station and get tested again after engine is warm.Afterwords go and fill it with more gas.Remember the more alcohal the betterbut no more than a gallon the the mix.It worked for me in ct with a 79 muscle car malibu and my numbers were of the charts.
