ive noticed that my speedo doesn't work when it is cold. it goes in and out sometimes when a hit a bump. i checked to see if the vss is plugged in and keep pushing it in. but the weird thing is it works fine only when the car is warmed up. what might be the problem? thanks

 

bump

 

hmm....i had the same prob and i just pushed it in and it never gave me a hassle again.

VSS's go bad you know.......maybe thats it

 

bump

 

check for loose wires first, and then i guess the next thng would be to replace the VSS.
