1500 rpm miss, sluggish and bad MPG

[iceplorer]

Hey there in the USA.

I went to my FORD dealer here in Iceland looking for a O2 sensor. He told me it costs 400$ !!!
What does it cost in the USA ? I bought some stuff to spray into the throttle-body to clean the system from a-z,
hope it´s enough.

about $45 each here. My 94 has 2. I know 91's have 1.

maf sensor

Hi
I have found the problem in My Explorer, I took it to my Ford service-station yesterday and the guy plugged it to a computer and the trouble-code was "157" MAF sensor below minimum voltage. I have cleaned it twice an checked the connecting plug to it and that seems ok. The sensor it self seems to be bad but I still have to measure it with a volt and ohm meter.
Can you guys tell me what a MAF sensor costs in the USA?
Thanks Iceplorer.
