I drove my frineds G37 into work today and it almost shut down on the highway. What could be wrong?
I got the car to the side of the road and it would not get above 1000 rpm before it shut down. I shut the car down and turned off the heater. Then I started it back up and it ran fine. Then when I got to my exit I saw the temperature run up from normal to hot. I shut it down and popped the hood to find that the engine did not seem hot at all.
