1994 Ford Thunderbird LX 4.6L MIL Lamp on
The problem that I`m having is that after replacement of the O2 sensors and tune up components listed above is that the SES engine lite came back on! Check the codes again and PO174 was there again. So i figured that possibly i have a defective new O.E. Sensor...
