SO i replaced one coil andall new plugs a few days ago. Still had a miss, after reading about the unplug method I found the next culprit. Yesterday I replaced that coil, left the battery unplugged for 30,reconnected it ...No codes, no miss.

This morning on my way to town, the SES light back up, stopped to check it and surprise...P1320 is back.


Please chime in with ideas

i've been stuck with this code as well! i replaced a coil and all my plugs about 7 months ago and I've read that it might have to do with the after market coil having slightly different voltage than the other 5 coils. Not sure if this is true though. Any help is appreciated!

 

IM HAVING THE SAME PROBLEM REPLACE THE PLUGS AND COILS AND YES P1320 IS BACK.I DONT KNOW WHAT IT IS... NEED HELP

 

not sure what brand coils you purchased but sometime if its not oem it will not go away...our cars are just so sensitive about the coils
