Time for this week's new puzzler. And it is new this week, I'm happy to say.

Years ago, an older gentleman came into the shop. And he gave me this puzzler. He said he thought we could use it. So here it is. 

He was driving his old car, an old Chevy from the 60s or 70s, so a really old car. He is driving along out on the highway. All of a sudden, he hears a noise like he's driven over something in the road. 

And he thought, "Oh my god, what was that?"

Immediately after that, he feels this incredible vibration from the engine. So he slows down to about 5 or 10 miles per hour. The vibration is still there, but it is reduced because he is going slower now. After a bit, he tries to speed up, and the vibration gets worse. It is shaking like crazy. 

So, he stops the car. He turns it off, opens the hood and everything looks okay in there. He looks under the car and everything looks okay there too.

So, he slowly makes his way to the nearest gas station. The gas station attendant looks at the car and can't find anything wrong with it. He has the guy start the car, and then says, "Shut the car off for a second." The owner shuts the car off. Then the attendant says, "Ah ha! I see what's going on here."

The attendant spends about 30 seconds under the hood of the car. He takes something and throws it in the trash. Then he says, "Okay start it up. I fixed your problem. The vibration is all gone."

And the driver says, "Am I gonna make it home okay?"

And the attendant says, "Yes, if you don't get stuck in traffic for too long. Make sure to get it fixed when you can though."

What was wrong with the car?

And the hint is, the car was from the 60s or 70s. But it is unlikely that the car was from the 90s.

Good luck.
