Big problem?, engine knocking... Options

[JFrost9]

Well its kind of an intricite problem... not only is my engine occasionally knocking, but when it goes to idle it dies on me, and i have trouble starting it back up... The oil should be good, its not too full or too empty, and was changed around 900 miles ago... The temp guage on my speedometer is past the H, and so im not driving it anymore, but i dont know what this problem is...or how to even diagnose it. I had smoke coming from the head for like 5 seconds, but it hasnt done it since... Anyone have any ideas?

Thanks in advance for any help.

When 22 IS the Engine Coolant Temp Sensor which means that there is a open or short circuit in coolant temperature sensor signal. And since your car idles and dies, which probably means that the sensor is telling your ECU your car is super super super hot and it probably shuts the car down? I don't know but check the sensor. Usually when a car over heats, it dies. Your coolant is needed to keep your car cool at Idle and since the computer is reading no coolant, that's pretty bad. I don't know about the knocking though. You might have killed something while driving around with a bad sensor?
