alright when I am idleing at a stop light or stop sign something for a little while. the tach will go down to 500 then back up to 1000 then slowly all the way down to zero. then it sounds like the engine restarts it self then is fine for a little while. whats kausing this to happen??? I just replaced the drive belt and all the plug boots and wires so that isnt the problem. any one else had this happen???
The picture attached is a piece that i found laying down in a crack on the engine when i was working on it, anyone know what it is or where it is supposed to go? it was laying under the TB.
