Here are the symptoms again. The car will not do it, if it has been sitting for more than 8 hours. I start it, and no tapping. But...If I drive it for about 5 minutes, I hear it when I come to a stop. But, it goes away after about 5-10 minutes. This noise only lasts in spurts of 5-10 minutes. If the car sits for about 1-5 hours, and you start it. It will tap. But, if I drive it for another 5-10 minutes, it will stop. Sometimes I can hear the tapping as the motor is turning just doing about 35 mph, after 1 hour of driving. Maybe I am just listening too close. Please help! I think the video amplifies the noise about 2x. If you guys need any more info let me know.

No suggestions?

 

what the!!!...

 

What does that mean?

 

Have you done an TB clean? If so, have you dropped dirt in there while doing this? Thats sounds like a lawnmower.

 

Yes, I have done the throttle body cleaning. I am thinking it could be exhaust manifold.
