What sensor is this??

A picture or better description would be cool... if its the one im thinking youre looking at, i believe its the water temperature sensor.
 
I swapped out intake's and am wondering what this sensor does...it's located at the right front side of the lower manifold.


Thanks, Dave

if passenger side its probably the ECT, which tells the computer the temp of the engine coolant. if driverside it is likely the ACT which tells the computer the tmp of the air charge. but, yes we need a pic to be certain.
 
I think its your ACT sensor, its kinda pointy and i have seen them with carbon buildup, kinda black and sticky but mostly dirt, get it replaced with a new one, when dirty can cause hesitation on WOT.
 
Here is the original source of the pic:

Maybe you can make it work from its originating source. If not, get with Tim (Stang 22 - that's his webpage).

I'm a real computer moron and don't know how to help ya otherwise. Were it me, the best I'd know to do is save it on my puter and resize it from there.

Good luck.
