I have a 2000 gtp with 157000 miles on it. While driving down the highway even with the cruise set the engine shuts off for a millisecond and the tach stops working. Car continues on its way with no issues except that he tach is not working. Once I can stop and restart the car the tach works again and everything is fine. Usually on the way home the same thing happens and the process is repeated.
The other issue I have is the abs light and traction control light is on. I know this is a faulty speed sensor but how can you tell which side needs to be replaced. Don't want to replace both.
Any help with these issues would be greatly appreciated. Thanks.
