Tonight while I was cruising around town, I noticed a problem with my car. Whenever I would come to a stop, the car would start vibrating, the rpms would slowly go down and then back to normal, and it almost sounded like something was clicking from the front of the car. It would not do it everytime, seems like after the car has been running for a while it would start to do it again. When I accelerated from a stop, it seemed to go away

mine was doing that, the egr vavle was sticking. Push the diaphragm on the egr valve and see if it sticks/moves roughly. If it does that it's your problem

 

Check the plug wires.
