P0102 p0103 fixed with new maf sensor but car falls flat at wot
Swap is out of a 02 ws6...Long story short car died on me and had p102 and 103 codes...I previously knew the maf sensor needed to be replace but the car died because the fuel filter before the fuel pump got clogged. Fram g3...replace it with a new one and a new fuel filter(acdelco)...and got a new maf sensor...fired up the car let it idle for 5 min...no codes! Took it for a short drive...but whenever I got on it wot the car took off then then hesitated almost instantly and basically fell on its face...got on it one more time in 2nd gear and did the same thing...pulled in the drive way and the only code it's giving me is p0650...possible lose connection at the pcm???and thoughts or input is welcome thanks!

Yea I'm going to get a fuel pressure gauge hooked up and check the psi....swap has been running fine for well over a year...I had the pre filter between tank and walbro 255 then I had an acdelco fuel filter post fuel pump

UPDATE!!!
when I bought the car the old owner (which phone is no longer in service) said the maf sensor never worked but he had it street tuned and he mentioned something along the lines he recommended I get a SD tune if I ever add a cam...
Out of curiosity I unplugged the new maf sensor and got a p0102 error code again but the car hauls *** now at wot...
Is it possible that the new maf throws the old street tune out of wack???
