I was driving my car to work it was going fine then all of a sudden it started clicking I pulled off to the side of the road and lifted the hood. The car wouldn't idle or anything someone had to press the gas for me to keep it running. It sounds so horrid, sounds like a lifter is just rattling around in the head or something. If you accelerate it just gets even worse and has no power like it's running on 2 cylinders. My guess is a lifter crapped out on me or head cracked. Anyone else got an idea?
