Recently acquired a 01 explorer 4.0.....and this is just there, looks like it been pulled out or broken off of somewhere else....any ideas, thanks in advance

 

Ok button not clickable because engine size is not selected. If you are NOT sure provide your VIN here.
Is it 2WD?

 

2wd 4.0
it a connector

 

I know it's 4.0L but 3 possible choices still, that's why I need your VIN to tell which one. Perhaps you don't feel comfortable providing your VIN here, what is the 8th character of your VIN. K or X or E?

 

The 8th letter is E

You don't need to buy the knock sensor w/ pigtail if you trust your previous owner with the ugly quick connect splices or you think your knock sensor is working fine.
You also don't need to buy the repair harness if you can depin the broken wire, and repin 2 new wires into it with a kit like .

 

Thanks, I appreciate it
the explorer doesn't like to take throttle past half pedal, it bogs in and out past half throttle...maybe this why
