Solved 1991 Ford Explorer Upstream O2 Sensor

[Damone Moore]

Good afternoon everyone. I have a quick question. On the 91 X 4.0L V6, is the oxygen sensor a "4 - prong" pigtailed one? I was driving and the truck ran out of gas, after being on a full tank for a little over a week, 170 miles driven. There is nothing wrong with the TPS, MAF, fuel pump or filter. I know this is the culprit, it's burnt up. I want make sure I get the correct one. Any part numbers would also be helpful. Thanks so much in advance...D

Thanks bro. I actually ordered one about an hour ago. After looking at so many and triple-checking and quadruple-checking if they were compatible with my year, make n model, something told me to get the Bosch brand. I guess I was lucky :-D
Thanks XLT, preciate it bro!!!!!
