I don't think the 88 had o2 sensors. I had the same thing happen to me in az . the rules stated that if the repairs were to be over 700 you could get a waiver. I went to a shop that advertised. that you would pass or the service was free , Firestone I think. they said I had a bad cylinder probably a bad valve and the cost to repair would be 800 . took it to a special DMV repair center who checked the report and he said I had a bad valve and gave me a waiver.
