replaced MAF and O2s, codes got WORSE
After my CEL came on on my 94 ranger 4.0, i read it and replaced the MAF and O2s now i get these codes....
179 Fuel system was rich at part throttle Single, Right or Rear HO2S - Fuel control
114 IAT sensor out of range - IAT
116 Engine Coolant (ECT) sensor out of range
157 Mass Air Flow signal is/was low or grounded
173 Oxygen sensor not switching - system is or was rich - Single, Right or Rear HO2S
188 Fuel system was rich at part throttle - Left or Front HO2S - Fuel control
What's wrong?
