Here's what happened! I didn't know what I had done with my truck, I had a check engine light on that was flashing.. had no power, the truck was basically running on about 3 cylinders. After trying many things I stupidly drove to advance. When I got to advance and it showed the codes for mis-fire 1, 4 & 5. Also the cat was glowing red hot.
Well, I switched the wires on 4 & 5.. that made them fine. 1 was a cracked spark plug and I replaced that. No more check engine light.
It ran "better" still little power.. I know the spark plugs and wires are done and fine BUT now, three days have passed and I have a hesitation and it idles a little rough. It's like it's choaking for air but I think it's the cat... I think I may have damaged what was left of it.. The truck was getting slower before and thats why I did my 100,000 mile tune-up.. maybe the cat was getting more and more clogged and I just managed to **** it off the other night with all the mis-fires.. Does this sound right??
