I recenly installed a K&N FIPK kit on my stock 03 cobra. This is the first mod on the car. The car starts and runs fine most of the time, but on occasion it will die when I put it in neutral, say coming up to a stop light. Also, does anyone know what rpm theses cars should idle at...Mine is idleing at 500-600 RPM which seems a little low? I double checked to make sure all electrical plugs and vaccum lines are hooked up correctly, although I left out the screen inside the MAF. Anyone know if these cars take time to "learn" this mod?? Should I have the car tuned? Any knowledge on this would be appreciated. Thanks guys
