my friend heather just called me saying she was driving with her cruise control on, and then all of a sudden the rpm gauge and speeo dropped to 0, she pulled over and turned it off, and when she started again it was fine. then i got another call 5 minutes later, and she said it did it again while at a stop sign, any ideas what could cause that, or what i could tell her to do? thanks

 

To not use the cruise control? :dunno:

 

What kind of car?

My Accord does that sometimes, appears that Honda had an issue with the Vehicle Speed Sensor after they switched from the cables in 94. See if it throws a code.

 

i told her that, but then she said it did it again at a stop sign...while not using the cruise, so i don't know, that's very weird.. she said all these guy friends she has said they would look at it, i'm like wtf are they going to look at they're just trying to act like they know what they're doing..

 

The gauges flatlined, but the car kept running fine? :dunno:

Hmm.. what model car is this? Sounds like some strange electrical problem to me.... a fawked up harness somewhere. :eh: Or a bum VSS.

A mechanical speedo wouldn't do that, for instance...so this must be a new-ish car. :thinking:

 

it's a 97 ford contour.. her check engine light has been on for a long time, but since it just did that, the CEL went off :dunno:

 

yeah car kept going... strange electrical problem indeed

 

Ask her to check the code. If the CEL was on and it wasn't checked then there could have been a problem that got worse.

 

well the CEL went off now, so she can't quite check the code

 

Code should be registered on the computer.
