Sorry I’ve tried search cause I don’t wanna be “that guy” asking the same questions and 50 different people but can’t seem to see anything that’s like my problem or may be I’m not search the right problem... so here goes y the way thanks guys!!

I bought a 88 Toyota truck auto v6 4x4 extcab from my boss ac works $1000 one owner every receipt from 1988to present on maintenance over $23,000 spent on it since 88 well maintained truck I been driving it for month or so now and all the sudden I started losing power then it ran fine the next day then the next day same thing losing power, now literally it won’t hardly pull it self out the driveway it kind of pops and spudders when you give it throttle in gear you can put it to the floor and it almost dies like dead pedal and it won’t get out of its on way, but in neutral it seems to rev smoother and maybe more responsive pedal.....
- right before I bought it head gaskets were replaced
new cap,button,wires and plugs not sure if knock sensor and pig tail was done though
- a buddy had a new coil we tried but no better
-checked timing its good
-replaced fuel filter
- I also pulled three codes 11 power supply, 41 TPS, 52 knock sensor but knock sensor is the only one that’s came back a couple time
-sprayed carb cleaner to check for leaks

im leaning towards replacing knock sensor but won’t some advise before I pull it in the shop and tackle that

any help would be greatly appreciated thanks
