Vss necessity?

[4x4man514]

Hey guys a lot of you have already told me the vss was Not necessary for running efi with a manual tranny. Some of you say it is.

Here's my question, if I'd rather play it safe than sorry , what type of sensor do I need? Would a 1990 f250 have one?(donor vehicle) if not can I get one at a parts store?


Reason I'm trying to find out all this now is my body is off and I'm trying to tie up the last few ends before reinstalling it. Today I was taking care of my back up lights switch and the vss I have now.

Thanks a lot guys!

The VSS is not a necessity, but if you're cruising along at 60 and come to a stop, the engine will fumble while the computer tries to figure out why everything isn't running like it was a second ago. I also saw a little better gas mileage when I put my VSS in.

I got mine from Wild Horses.
