Got this BS fixed doing a throttle relearn with the VCM scanner, Ty HPT for this wonderful tool
I'l be damned, i guess that i should have done that throttle relearn when i switched PCM's, my stock one is safely stored in a box somewhere in my garage, and the one i have now, is a used one i bought from ebay.
Couple of months ago when i did the switch, i didn't do anything especial other than clearing out some DTC's, i don't believe HPT instructions said anything on this sort either after having a new PCM reflashed with your factory calibration, never noticed any other issues but this one with the throttle being super laggy while going from close throttle to open with the car moving, now this biatch is actually very nervous whith the most minimum throttle input, i'm barely touching the gas with the car moving, and my neck will start snapping right away, lol, oh well, live to learn, and i'll keep learning from this platform.
