About four months ago I changes my battery in my 97 Intrepid 3.5. As soon as I left the garage every time I slowed for a turn or a stop it would stall.I had no problem prior to this.After a long summer of changing parts from my local salvage yard I was lost and confused.The reader kept suggesting the IAC but it never set any codes.Finally one day I looked at the electic/vaccum switch for the EGR.I sprayed gum cutter in the hoses and started the car up.I went for a spin and the car ran perfect.I can,t believe how good it runs. I don;t know why it acted up by changing the battery or why no codes set and why the reader showed everything including the EGR was working. But It runs fine now
