Chrysler Repair/2.7L backfiring


2000 concorde 2.7 i put it in time and its back firing through the intake why?

Hi Derrick,
Try the on-board fault code readout: "on-off-on-off-on and leave on" using the ignition switch, doing that in 5 seconds or less elapsed time. Then watch the odometer window of the cluster to see the mileage reading change to show a 4-digit number(s). Let me know what they are.
I don't know what you mean by 'put it in time' as there is no way to adjust the spark is controlled automatically. Tell me what is the history and what have you done.
Please 'rate' my answer (see the PS below).
