Decrease in Acceleration

[Toothless]

I'm having a decrease in acceleration when I just push it. I've reset the PCM due too cleaning my TB, IAT sensor, and MAP sensor, I haven't change my oil in 6k but doing that this weekend and my transmission oil oil 70k old. The truck has 70500 Miles on it. Original plus and coil. Pretty much I need to know what I need to update or would want to update on my truck.

I have a 5.7L, trying to take care of it the best I can without going over board, that'll come next year after I get back.

Thanks

^^^Manual calls for plug change at ~ 32K miles. I'd start there.

Original spark plugs at 71k.

I originally said I was going to do this on the 4th of July but got delayed.

All 16 were champion plugs OEM from factory. Swapped them with NGK 5306 V-power copper core

I see a bunch of broken insulators....So what does the butt dyno say after the new plugs?

Well i just got done 30 mins ago took a stroll down the high. Couple cars were trying to keep up. Granted they were 4 banger tuner Hondas. I am happy now for the transmission and o2 sensor and fuel pump eventually
