O2 Sensors
 

How much for a set of lower O2 sensors near the x/h pipe? Or should i just hit up a local shop/ford dealship?

what model and year?

shit, my bad....01 GT

ok, just had to make sure.
frt O2' are $74.90 each and the rear O2 monitors are $77.50 each

I paid 58 for one there from stanard same as ford but less cash.

they are NOT the same as Ford, you bought aftermarket and they DO NOT work as good or last as long the OEM ones.
you got owned:ohsnap:

Oh man . Thats all i need.:shakeno:

live & learn bro, thats why we are here.

Fords are VERY sensitive when it comes to electronics, esp sensors.
FoMoCo has companys make these parts to work wthin certian parameters on there products
ie: for example lets say "A to D", then the aftermarket companys make these same "looking" parts for a parts stores but the open-up these parameter to, say "A to G" so that same part can fit many other models, makes and years. now you've installed a product that might have greater resistance and reads differently then Ford designed it to and now your car doesn't operate like it should
