89 iroz z with 5.0 tpi throwing 3 codes
Hey my z is throwing 22, 33, and 44 codes which are all sensors but the O2, MAF, and TPS are all brand new so probably the MAP or does it have both the MAF and MAP sensors?

Yes it does have a mass air sensor and a map sensor. Code 22 is tps voltage to low. Code 33 is map sensor out of range. Code 44 is O2 sensor lean exhaust. Did you clear the pcm after you replaced the sensors?
