My dads SC was pinging under load. He was at 1/4 tank when it first happened he and I figured it sloshed and went lean. He filled up and it was still happening. He brought it over and I saw a two huge vac leaks off the bat. We plugged them up and he said the idle under load was now smooth. We figured all was well and as he was pulling away and barked the tires and put some load on it and it was pinging bad but also a little black smoke. He circled back and I smelled sulfur (car has cats) He was leaning towards fouled plugs I was thinking bad gas as idle is smooth. He filled up at Arco. I’ve got a bad tank there before so maybe I’m biased car is on the ragged edge of “should be pinging” but never has. 92 auto 30# injectors.
