pfc reset ruins accel. need help
alright so i've been haveing a problem for a few months where my idle stuck at 2.5k and i finally fixed it by reseting my pfc and then it idled fine. but now if you hold the gas the rpm's surge and it drops back to idle then goes back up and so on untill you let off the gas and then it idles fine again. i made a video showing what it does heres the link

One thing I noticed is the voltage of the TPS is way off.
THe video showed VTA1 4,85 and VTA2 4,97
Mazda's Standards are:
VTA1: closed 0.10 to 0.70. open 4.2 to 4.6.
VTA2: closed 0.75 to 1.25. open 4.8 to 5.0.
This is with the fast idle cam disengaged.
