Delco 41-985 spark plug
I just changed the plugs in my car the other day and these were the plugs that I took out. I put in some TR6's along with some MSD wires and everything seemed good, drove around town fine and when it would just get on it real quick it seemed fine. But last night I got on it in 3rd and stayed in it and the CEL start flashing at me and the car felt weak. So when today I rechecked all the wires and went for a drive and the CEL didn't flash or anything but the car felt no where near like it used to. I have the TR6's gapped at .38 and I'm thinkin that maybe the plugs are getting blown out?? So should I try gapping them around .28 or so and just stay with the TR6's or go back to the delco's? The gap was .28 on the delco's FYI. Thanks alot guys

So do yall think it was just the gap being the deciding factor or the plugs themselves?
