what do these codes mean??
i ran the codes on my 95 mustang gt and came up with these
181 o2 sensor voltage not switching: indicates lean during part throttle operation bank1
189 (same as 181 except its bank 2)
157 MAF sensor signal votage to low
332 insuffient egr flow
i do not have my egr connected to my exhaust but it is connected to the TB and the sensor is still plugged in. i just wanted to know if the o2 sensor codes were from the MAF or vice versa.

clean the MAF sensor's Internal Element and make sure it is mounted vertically, not leaning to the side at all.
The 02's are ok, the MAF Is not registering enough air for some reason
