Default 92 4.9L Acceleration issue

Got a slight problem that I think is related to my transmission issues. Currently if im trying to accelerate from say like 25 up to 35 and I don't mash on the gas it is absolutely the slowest acceleration ever and maybe i'll get up to that speed in like 5 minutes lol. However if i kind of mash on the gas a little it will accelerate quickly and I'm a happy person then.

I'm wondering would a TPS be the cause of this issue? and does that effect transmission shifts?

If it's the TPS is there a way to try to bring some life back into it or is a new one the only option

Is your CEL on/is it throwing any codes? Could be a lot of things.

check engine light is hit or miss. Sometimes when im driving it will come on, other times it wont. And this problem happened yesterday, no light on. And I think the light comes on typically due to my O2 Sensor being completely dead. But i have pulled the codes, most of which pointed me to my O2 Sensor, Coolant Temp Sensor, and EGR

What are the actual codes? Start with KOEO. There's no sense at all in trying to figure out a performance issue until you resolve all problems the computer knows about.

I'll go pull them again. I have cleaned up a few things since I checked them the first time. I'll take a video and get it up here so you guys can double check my counting

What about koeo? Those need to be checked and resolved first.
