My idle was off so I checked the specs on the tps and it needed to be adjusted. So when I went to adjustto it I noticed it was missing a screw.

I'm being a bit lazy so I don't want to take the other screw out to match it up. I plan on changing them to allen heads. Does anybody know the size I need?

 

Almost certain M6, should be more than a sufficient number of 10mm hex head fasteners you can pull off throughout the car to check. Length, I'd guess in the 12~15mm range from distant memory, should be easy enough to find out via the same method....just don't bottom and keep on turning!

 

M4x12mm

 

Thanks for the replies. The m4x12 was it. I just picked up 2.
