TPS is set to .45 No one has messed with the throttle bodies of my knowledge. I have replaced all coil packs because the old were arcing out of the boot Injectors are firing and within spec I haven't checked for vaccum or boost leak but I don't believe that's the problem because at times it would run absolutely fine which would lead me to believe if it were a boost or vaccum leak it would do it constantly. And it runs worse when unplugged so the maf is fine
