As a newb you might not know how to adjust the TB or even how it all works. The TB also might not be set up correctly.
PM arghx about joining the private PFC Tuning Group. One tuning paper tells how to totally check and set up the TB.
Did you remove the 4 PFC connectors or cut their wires or at lease remove their terminal connectors?
(1) Insure that the hot wax rod unit is totally disengaged when the engine is warmed up.
(2) Insure that the linkage has slack so the TB is 100% closed.
(3) Check and record the closed and fully opened TPS voltages.
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.
(4) Fix all problems.
