rough idling and engine temperature gauge not working
First, the temperature gauge stays completely cold most of the time, however it does move occasionally after start up, but stops working (goes back to fully cold) after a little while.
Also, while idling, the engine revs at 1200, then drops suddenly to 800 rpm, and repeats over and over until the car starts moving. This problem doesn't usually occur until after the car has been running for a little while.
I think the two might be connected, and its probably a problem with the engine temperature sensor.
Anyone else have a similar problem or any ideas?
