i installed a remote starter on a 2003 mazda 6 for a friend and they tell me that is has dies a couple times while idle at a stop light but not all the time. we did disconnect the battery so i am not sure if that would have caused a problem or not. also i unplugged a bunch of plugs trying to find the door lock module under the driver side dash. i eventually found it on the passenger side and got everything i need. i could have possibly forgot to plug one of the plugs under the dash but i dont think i did. just wondering if this has happened to someone else or have any ideas what to check for the problem. thank you for any help in advance

 

could be a loose wire, check the wires going to the spark/glow plugs and then to the ignition controll.
